When did Guido of Arezzo live?
Guido of Arezzo
Guido of Arezzo (also Guido Aretinus, Guido Aretino, Guido da Arezzo, Guido Monaco, Guido d'Arezzo, or Guy of Arezzo also Guy d'Arezzo) (991/992 – after 1033) was an Italian music theorist of the Medieval era. He is regarded as the inventor of modern musical notation (staff notation) that replaced neumatic notation. His text, the "Micrologus", was the second most widely distributed treatise on music in the Middle Ages (after the writings of Boethius).
Margaret Guido
Guido was born Cecily Margaret Preston on 5 August 1912 in Beckenham, Kent. Peggy was the eldest of two children to Elsie Marie Fidgeon – whose father was of independent means – and Arthur Gurney Preston, a Cambridge-educated engineer and wealthy ironmaster, who is also recorded as of independent means at the time of her birth. Peggy's family home was a twenty-room mansion, Wood Lodge in West Wickham. During her childhood, her mother remarried, and during the summer of her eighth birthday her father drowned in Cornwall, after which she was brought up by her aunt.
Guido della Torre
Guido della Torre (27 September 1259 – summer 1312) was a Lord of Milan between 1302 and 1312.
Guido (slang)
Guido is a North American slang term, often derogatory, for a working-class urban Italian American. The guido stereotype is multi-faceted. Originally, it was used as a demeaning term for Italian Americans in general. More recently, it has come to refer to Italian Americans who conduct themselves in an overtly macho manner. The time period in which it obtained the later meaning is not clear, but some sources date it to the 1970s or 1980s. The term is not currently used in Italy.
Guido Island
Guido Island () is an island lying northeast of Prioress Island in the Wauwermans Islands, in the Wilhelm Archipelago, Antarctica. It was shown on an Argentine government chart of 1950; the name "Isla Guido Spano" appears on a 1957 chart and is for Carlos Guido Spano (1829–1918), a famous Argentine poet.
Piero di Cosimo de' Medici
Piero di Cosimo de' Medici (the Gouty), (Italian: "Piero "il Gottoso"") (1416 – 2 December 1469) was the "de facto" ruler of Florence from 1464 to 1469, during the Italian Renaissance.
Guido I da Montefeltro
Nonetheless, Guido emerged back into public life in 1288, when he was excommunicated and became captain of the Ghibellines of Pisa. Over the next few years he aided Pisa in its struggle against Florence, and the city of Urbino against Cesena.
Guido da Velate
After the death of Henry III in 1056, Hildebrand, Anselm of Baggio, and Peter Damian were sent to settle matters in Milan, but to little avail. The peace they brokered was broken incessantly until 1067, when Guido gave up his see and recommended the subdeacon Gotofredo da Castiglione to the Emperor Henry IV (for a price). Guido was convinced by Anselm of Baggio, now pope, to repent of his abdication and return to his post. He died a few years later and Henry tried again (uncanonically) to appoint Gotofredo.
Arezzo Cathedral
In the counter-façade is the hexagonal baptismal font, with reliefs by Donatello's workshop, including a "Baptism of Christ" by Donatello himself. The Chapel of the Madonna del Confort is a Neoclassicist work, built from 1796 and housing several terracottas by Andrea della Robbia. In the same side is the cenotaph of Guido Tarlati, lord of Arezzo until 1327. According to some, it was designed by Giotto, and executed by Agnolo di Ventura and Agostino di Giovanni. Near to the cenotaph is Piero della Francesca's "Mary Magdalene" (1460s).
Guido de' Medici
Guido de' Medici (died 1537) was a Roman Catholic prelate who served as Archbishop of Chieti (1528–1537) and Bishop of Venosa (1527–1528).

Guido of Arezzo
Guido is credited with the invention of the Guidonian hand, a widely used mnemonic system where note names are mapped to parts of the human hand. However, only a rudimentary form of the Guidonian hand is actually described by Guido, and the fully elaborated system of natural, hard, and soft hexachords cannot be securely attributed to him.
Guido I Embriaco
In 1204 he married Alice of Antioch (c. 1185 - after 1204), daughter of Bohemond III of Antioch and his third wife. They had five children:
Guido da Landriano

Satyrus of Arezzo
Saint Satyrus of Arezzo (fl. 304 AD) is venerated as the first bishop of Arezzo. The "Catholic Encyclopedia" states that Arezzo "became a bishopric about 304, under St. Satyrus. St. Donatus, his successor, is patron of the cathedral of St. Peter the Apostle."
Arezzo
Described by Livy as one of the "Capitae Etruriae" (Etruscan capitals), Arezzo ("Aritim" in Etruscan) is believed to have been one of the twelve most important Etruscan cities—the so-called Dodecapolis, part of the Etruscan League. Etruscan remains establish that the acropolis of San Cornelio, a small hill next to that of San Donatus, was occupied and fortified in the Etruscan period. There is other significant Etruscan evidence: parts of walls, an Etruscan necropolis on "Poggio del Sole" (still named "Hill of the Sun"), and most famously, the two bronzes, the "Chimera of Arezzo" (5th century BC) and the "Minerva" (4th century BC) which were discovered in the 16th century and taken to Florence. Increasing trade connections with Greece also brought some elite goods to the Etruscan nobles of Arezzo: the krater painted by Euphronios c. 510 BC depicting a battle against Amazons (in the Museo Civico, Arezzo 1465) is unsurpassed.
Conquered by the Romans in 311 BC, "Arretium" became a military station on the via Cassia, the road by which Rome expanded into the basin of the Po. Arretium sided with Marius in the Roman Civil War, and the victorious Sulla planted a colony of his veterans in the half-demolished city, as "Arretium Fidens" ("Faithful Arretium"). The old Etruscan aristocracy was not extinguished: Gaius Cilnius Maecenas, whose name is eponymous with "patron of the arts", was of the noble Aretine Etruscan stock. The city continued to flourish as "Arretium Vetus" ("Old Arretium"), the third largest city in Italy in the Augustan period, well known in particular for its widely exported pottery manufactures, the characteristic moulded and glazed Arretine ware, "bucchero"-ware of dark clay and red-painted vases (the so-called "coral" vases).
Italophilia
Gregorian Chant, an outgrowth of Roman plain chant, strongly influenced both liturgical and secular music during the Middle Ages. An Italian monk, Guido of Arezzo (born in 991), developed the form of musical notation that became the basis of Western music and, subsequently, of music worldwide.
Federico da Montefeltro
Federico da Montefeltro, also known as Federico III da Montefeltro KG (7 June 1422 – 10 September 1482), was one of the most successful condottieri of the Italian Renaissance, and lord of Urbino from 1444 (as Duke from 1474) until his death. A renowned intellectual Humanist and civil leader in Urbino on top of his impeccable reputation for martial skill and honor, he commissioned the construction of a great library, perhaps the largest of Italy after the Vatican, with his own team of scribes in his scriptorium, and assembled around him a large humanistic court in the Ducal Palace, Urbino, designed by Luciano Laurana and Francesco di Giorgio Martini.
Guido (bishop of Turin)
Guido had a special care for the monastery of Santa Maria in Cavour, which his predecessor, Bishop Landulf of Turin, had founded. In 1041 Guido confirmed Landulf’s donations to Cavour, and also intervened to ensure that Adelaide of Turin ceded property to the monastery. Then, in 1044, Guido donated the church of San Secondo, located near the Dora Riparia river, to Abbot Alberic of Cavour.

Guido Monte
Guido Monte (born 1962 - died 2017) was an Italian writer and poet. In his mature works, he employed linguistic blending in the search for meaningful and archetypal relations between distant cultures.
His works and translations have been published by international magazines (as "Words Without Borders", "Swans Commentary", and "Ars Interpres"). On his blending experiments, he uses also Japanese, Sanskrit, Sheng and languages of ethnic groups in Kenya.
University of Arezzo
The University of Arezzo (Studium Aretino) is an ancient university founded in 1215 and located in the town of Arezzo in the Tuscany region of Italy which has declined in importance since it was overtaken by newer Italian universities. It has been recognized as a studium generale since early in the 13th century.
Bartolomeo Goggio
Bartolomeo Goggio (also known Goggi, Gogio, and Gogo) was an Italian author and notary. He was born in Ferrara circa 1430 and died sometime after 1493. He is most recognized for "De laudibus mulierum" [On the Merits of Women], written in the late 1480s, which was dedicated to Eleanor of Naples, Duchess of Ferrara. Only one surviving manuscript of "De laudibus mulierum", currently held at the British Library"," is known to exist. For this work, Goggio is recognized as a contributor to the pro-woman side of the "querelle des femmes" — "a debate about the nature and worth of women that unfolded in Europe from the medieval to the early modern period." In "De laudibus mulierum" Goggio argues the superiority of women. After Eleanor's death, Goggio wrote another philosophical work, "De nobilitate humani animi opus."

Medieval technology
Guido da Vigevano (c. 1280 − 1349) was the first author to add illustrations to his anatomical descriptions. His "Anathomia" provides pictures of neuroanatomical structures and techniques such as the dissection of the head by means of trephination, and depictions of the meninges, cerebrum, and spinal cord.
The Duchess of Padua
The Duchess of Padua tells the story of a young man named Guido who was left in the charge of a man he calls his uncle as a baby. Guido gets a notice to meet a man in Padua in regards to something concerning his parentage. When he arrives in Padua he is convinced by a man named Moranzone to abandon his only friend, Ascanio, in order to dedicate himself to revenging his father’s death at the hands of Simone Gesso, the Duke of Padua. In the course of the play Guido finds he has fallen in love with Beatrice, the title character, and confides his love to her, a love which she returns. By this time Guido has had a change of heart and decides not to kill the Duke of Padua, and instead intends to leave his father’s dagger at the Duke’s bedside to let the Duke know that his life could have been taken if Guido had wanted to kill him. On the way to the bedchamber, however, Guido is met by Beatrice, who has herself stabbed and killed the Duke so that she might be with Guido. Guido is appalled at the sin committed on his behalf and rejects Beatrice, claiming that their love has been soiled. She runs from him and when she comes across some guards she claims that Guido killed the Duke. He is brought to trial the next day. Beatrice tries to prevent Guido from speaking on his behalf for fear that she might be exposed as the killer, but Guido admits to the killing to protect her, and so the date for his execution is set. Beatrice goes to visit Guido in his cell and tells him that she has confessed to the murder but that the magistrates did not believe her and would not allow her to pardon Guido. Before waking Guido, Beatrice drinks some poison and when Guido discovers that the poison is all but gone, he shares a kiss with Beatrice before she dies, at which time Guido takes her knife and kills himself.Guido Ferranti, a young man, travels to Padua with his friend Ascanio after receiving a mysterious letter from a stranger, claiming to know the true secret of Guido's birth. Guido
meets him in the market, as the letter instructs, and after Ascanio leaves, he reveals himself as Count Moranzone. He tells Guido that his father was the Duke Lorenzo, who had been executed after being betrayed by a close friend in exchange for land, that his mother died in a swoon on hearing the news, and it was he who had taken the young Guido to the family he had grown up with. He encourages Guido in his revenge, and telling him that betraying the Duke is better than merely killing him, and shows him his father's knife. Before Moranzone can tell Guido the traitor's name, the Duke of Padua enters with his court, and Moranzone indicates the Duke's guilt by kneeling before him. He introduces Guido as one who wants service in the Duke's household. The Duke accepts him, then continues to the Cathedral. Moranzone tells Guido that until he is avenged, he should put aside all other things - when Ascanio returns, Guido sends him away. As Guido speaks a soliloquy, swearing this, he sees the Duchess of Padua pass. Their eyes meet.

Otto Orseolo
After Giovanni's sudden death (1006), Pietro raised Otto to the dogeship with him. He then made a testament, giving the majority of his wealth to the poor and the Church, and retired to a monastery, leaving Otto the government. When Pietro finally died in 1008, he left Otto sole doge at the meager age of sixteen. Soon after the death of his father, in 1009, Otto married a daughter of the newly Christian Géza of Hungary and Adelaide. She was called Grimelda or Gizella (989-992 - d. 1026). Because the "Chronicon Venetum" of John the Deacon ends in Otto's reign, it is necessary to rely on later chronicles. According to the chronicler (and doge) Andrea Dandolo, writing from a vantage point three centuries ahead, Otto was:
Scandal marked much of Otto's reign, as he showed a clear inclination toward nepotism with the elevation of several relatives to positions of power. In 1017, Vitale Candiano, the Patriarch of Grado, died and Otto appointed his elder brother (Pietro's second son), Orso, already Bishop of Torcello, to the vacant patriarchate. Otto then filled the vacant Torcello with his younger brother Vitale. These actions lost him the support of the people, though they did not yet clamour for his removal from office. The denunciations of Poppo of Treffen, the Patriarch of Aquileia, incited the Venetians to expel Otto and the patriarch of Grado from Venice, whence they took refuge in Istria from 1022 to 1023. But in that latter year, Poppo sacked the patriarchal palace and church in Grado and the Venetians recalled Otto and Orso.
Guido Guinizelli
Guido Guinizelli (c. 1230–1276), born in Bologna, in present-day Emilia-Romagna, Northern Italy, was an Italian poet and 'founder' of the Dolce Stil Novo. He was the first to write in this new style of poetry writing, and thus is held to be the "ipso facto" founder.
Roman Catholic Diocese of Arezzo-Cortona-Sansepolcro

Vidus Vidius
Guido Guidi (Latinized name Vidus Vidius) (10 February 1509 – 26 May 1569), was an Italian surgeon and anatomist.
Guido of Arezzo
In the 12th century, a development in teaching and learning music in a more efficient manner had arisen. Guido of Arezzo's alleged development of the Guidonian hand, more than a hundred years after his death, allowed for musicians to label a specific joint or fingertip with the gamut (also referred to as the hexachord in the modern era). Using specific joints of the hand and fingertips transformed the way one would learn and memorize solmization syllables. Not only did the Guidonian hand become a standard use in preparing music in the 12th century, its popularity grew more widespread well into the 17th and 18th century. The knowledge and use of the Guidonian hand would allow a musician to simply transpose, identify intervals, and aid in use of notation and the creation of new music. Musicians were able to sing and memorize longer sections of music and counterpoint during performances and the amount of time spent diminished dramatically.
Province of Arezzo
The north of the province of Arezzo contains the Pratomagno and Casentino mountain ranges and valleys, and the southern areas of the region contain the fertile Tiber and Chiana valleys. The province capital Arezzo was a major Etruscan urban centre known as "Aritim", and a wall was built around the province in this period of rule. In Roman times, the settlement was given the latinized name "Arretium" and expanded down from the hills. Arretium assisted Ancient Rome in the Punic Wars against Ancient Carthage. After attacks from barbarians, the settlement mostly disappeared in around 400 AD.
Guido della Torre
Being the head of the della Torre family helped Guido in his election to Milan’s Captain of the People in 1307. The following year Milan elected him as a perpetual "capitano del popolo". However, in 1311 Guido entered in conflict with his cousin Cassono della Torre, archbishop of Milan: after an unsuccessful attempt to raise the Milanese against emperor Henry VII, he was forced to flee, first to Lodi, then to Cremona where Guido died in the summer of 1312.
Gualfardo of Verona
Saint Gualfardo of Verona (or Wolfhard of Augsburg) (1070–1127) was a Swabian artisan, trader, and hermit who lived around Verona. A hagiographical "vita" (biography) was composed, according to the Bollandists, within decades of his death, probably towards the end of the twelfth century. In the early sixteenth century he was venerated as the patron saint of the harnessmakers' guild at Verona.
Guido Memo

He served as Archbishop of Corfù until his death on January 1705.
Guido of Siena
Beyond this, little is known of Guido da Siena and his place in Sienese painting before Duccio. Because he is the only Sienese painter of the time to have surviving works on panel with a signature, he is often viewed as the most important artistic personality at the time and the first master of the great Sienese school of painting. However, Bellosi has attempted to associate some "Guidesque" works with the names "Dietsalvi di Speme" and "Guido di Graziano", who are documented with the painting of Biccherna book covers for the Sienese commune in the 1270s. Some equate Guido as the father of Meo di Siena.
Guido of Arezzo
The "Micrologus", written at the cathedral at Arezzo and dedicated to Tedald, contains Guido's teaching method as it had developed by that time. Soon it had attracted the attention of Pope John XIX, who invited Guido to Rome. Most likely he went there in 1028, but he soon returned to Arezzo, due to his poor health. It was then that he announced in a letter to Michael of Pomposa ("") his discovery of the "ut–re–mi" musical mnemonic. Little is known of him after this time.

Paolo Burali d'Arezzo
Paolo Burali d'Arezzo (1511 – 17 June 1578) was an Italian priest of the Theatine Order, a bishop, and cardinal of the Roman Catholic Church. His legal skills made him a prominent figure in the law courts of Naples, and then in the councils of government as a defender of the rights of citizens. He abandoned his career to pursue a calling to the religious state, where he became a leader in the Theatine Order. Pope Pius V elevated him to the cardinalate in 1570. He was considered as a candidate for the Papacy in 1572, but his stern character did not recommend him to the electors. The new Pope, Gregory XIII, then promoted him to be the Archbishop of Naples, where he served from 1576 to 1578. After his death he was recognized as a saintly man and worthy of official recognition by the Church.
Guido Ascanio Sforza di Santa Fiora
Guido Ascanio Sforza di Santa Fiora (26 November 1518 — 6 October 1564) was an Italian cardinal, known also as "The cardinal of Santa Fiora".

Margaritone d'Arezzo
Margarito or Margaritone d'Arezzo ("fl. c." 1250–1290) was an Italian painter from Arezzo.
Little is known of Margaritone's life. The only documentary record of his existence dates from 1262, when he lived in Arezzo. However, a fair number of his works are known to survive; unusually for the time, most are signed. Their nature and distribution indicate that Margaritone was much in demand as an artist, both in Arezzo and throughout Tuscany. Outside Italy, his fame rests mainly on his entry in Giorgio Vasari's "The Lives of the Artists".
Guido Ascoli
Guido Ascoli (12 December 1887, in Livorno – 10 May 1957, in Torino) was an Italian mathematician, known for his contributions to the theory of partial differential equations, and for his works on the teaching of mathematics in secondary high schools.
Arezzo
The commune of Arezzo threw off the control of its bishop in 1098 and was an independent city-state until 1384. Generally Ghibelline in tendency, it opposed Guelph Florence. In 1252 the city founded its university, the "Studium". After the rout of the Battle of Campaldino (1289), which saw the death of Bishop , the fortunes of Ghibelline Arezzo started to ebb, apart from a brief period under the Tarlati family, chief among them Guido Tarlati, who became bishop in 1312 and maintained good relations with the Ghibelline party. The Tarlati sought support in an alliance with Forlì and its overlords, the Ordelaffi, but failed: Arezzo yielded to Florentine domination in 1384; its individual history was subsumed by that of Florence and the Medicean Grand Duchy of Tuscany. During this period Piero della Francesca worked in the church of San Francesco di Arezzo producing the splendid frescoes, recently restored, which are Arezzo's most famous works. Afterwards the city began an economical and cultural decay, which ensured that its medieval centre was preserved.
Guido delle Colonne

His messages were aired on TV stations in the Georgia and South Carolina region.
Guido Palmeruccio
Guido Palmeruccio, also called Guiduccio Palmerucci (active 1315–49),was an Italian painter, active in Gubbio. 
Near nothing is known of his biography, and it is likely some of the works attributed to this painter belong to followers or contemporaries. One name brought up in this regard is Melli or Mello de Eugubio (Mello da Gubbio). Guido's style seems to show influence of Pietro Lorenzetti. The works attributed to him include frescoes in the church including a "St Antony" on the facade of Santa Maria de'Laici in Gubbio. he painted a "Madonna and Child and Saints" for the Palazzo de'Consoli in Gubbio.
Tomás Guido

House of Medici
Piero de' Medici (1416–1469), Cosimo's son, was only in power for five years (1464–1469). He was called "Piero the Gouty" because of the gout that pained his foot and led to his death. Unlike his father, Piero had little interest in the arts. Due to his illness, he mostly stayed at home bedridden, and therefore did little to further the Medici control of Florence while in power. As such, Medici rule stagnated until the next generation, when Piero's son Lorenzo took over.
Gherardello da Firenze
Gherardello da Firenze (also Niccolò di Francesco or Ghirardellus de Florentia) ( 1320–1325 – 1362 or 1363) was an Italian composer of the "Trecento". He was one of the first composers of the period sometimes known as the "Italian ars nova".

Guidonian hand
In Medieval music, the Guidonian hand was a mnemonic device used to assist singers in learning to sight-sing. Some form of the device may have been used by Guido of Arezzo, a medieval music theorist who wrote a number of treatises, including one instructing singers in sightreading. The hand occurs in some manuscripts before Guido's time as a tool to find the semitone; it does not have the depicted form until the 12th century. Sigebertus Gemblacensis in 1105–10 did describe Guido using the joints of the hand to aid in teaching his hexachord. The Guidonian hand is closely linked with Guido's new ideas about how to learn music, including the use of hexachords, and the first known Western use of solfege.

Odo composed a tonary (a book of chants which usually included antiphons and responsories) with a discussion of modes, which survives in 20 manuscripts, four of which contain attributions to Odo. In several of the manuscripts a prologue ascribed in three out of six to Odo is entitled "Formulas quas vobis".

The city is mentioned in the writings of Gregory I (590–604). Adrian IV (1154–59) was the first pope to spend significant time in Orvieto. According to the "Catholic Encyclopedia", "on account of its position, Orvieto was often chosen by the popes as a place of refuge and Adrian IV fortified it." His successor, Innocent III (1198–1216), was a militant opponent of the Cathar heresy, which had infiltrated the city, and took measures to eradicate that heresy; Innocent III sent Pietro Parenzo to govern the city, who was quickly martyred. In 1227, Gregory IX (1227–1241) confirmed the Dominican "studium generale" in Orvieto, a school of theology, one of the first in Europe.

Candidus (floruit 793–802)
Candidus was the name given to the Anglo-Saxon Wizo or Witto by Alcuin, whose scholar he was and with whom he went in 782 to Gaul. He is author of several philosophical texts wrongly attributed by earlier scholars to the benedictinian monk Brun Candidus of Fulda, the author of the vita of Abott Eigil of Fulda. But recent research into the manuscript tradition furnishing clear evidence attested the authorship of Candidus Wizo, the learned disciple of Alcuin. Based on his deep knowledge of the works of Saint Augustine of Hippo he tried to give proof of god’s existence, to demonstrate that the incorporeal nature of god is conceivable only by means of the spiritual eye and excludes any possibility of viewing him by means of the corporeal eyes, and to elucidate the problem of the incarnation explaining its need by the weakness of the human cognition. At the palace school he was tutor to Gisla, the sister, and Rodtruda, the daughter of Charlemagne. When Alcuin went to Tours (796), Candidus was his successor as master of the palace school. Alcuin's esteem for Candidus is shown by his dedicating his commentary on Ecclesiastes to his friends Onias, Fredegisus, and Candidus.
