Avicenna
Avicenna was born in Afshana, a village near Bukhara (in present-day Uzbekistan), the capital of the Samanids, a Persian dynasty in Central Asia and Greater Khorasan. His mother, named Sitāra, was from Bukhara; his father, Abdullāh, was a respected Ismaili scholar from Balkh, an important town of the Samanid Empire, in what is today Balkh Province, Afghanistan. His father worked in the government of Samanid in the village Kharmasain, a Sunni regional power. After five years, his younger brother, Mahmoud, was born. Avicenna first began to learn the Quran and literature in such a way that when he was ten years old he had essentially learned all of them.
Vincenzo Coronelli
Vincenzo Coronelli was born, probably in Venice, on August 16, 1650, the fifth child of a Venetian tailor named Maffio Coronelli. At ten, young Vincenzo was sent to the city of Ravenna and was apprenticed to a xylographer. In 1663 he was accepted into the Conventual Franciscans, becoming a novice in 1665. At age sixteen he published the first of his one hundred forty separate works. In 1671 he entered the Convent of Saint Maria Gloriosa dei Frari in Venice, and in 1672 Coronelli was sent by the order to the College of Saint Bonaventura and Saints Apostoli in Rome where he earned his doctor’s degree in theology in 1674. He excelled in the study of both astronomy and Euclid. A little before 1678, Coronelli began working as a geographer and was commissioned to make a set of terrestrial and celestial globes for Ranuccio II Farnese, Duke of Parma. Each finely crafted globe was five feet in diameter (c. 175 cm) and so impressed the Duke that he made Coronelli his theologian. Coronelli's renown as a theologian grew and in 1699 he was appointed Father General of the Franciscan order.
