List of Welsh-language poets (6th century to c. 1600)
Much of Welsh language poetry has, until quite recently, been composed in various forms of strict metre (canu caeth), latterly with the encouragement of the eisteddfod movement. The following list is as inclusive as possible for the years prior to 1600. It includes as many minor poets as possible to illustrate the range and content of Welsh poetry throughout the ages. However much early poetry has been lost, and much medieval verse is either anonymous or, usually in the case of mythological poems and prophetic verse, attributed to the 6th-century poet Taliesin or the mythical figure of Myrddin. Early religious and gnomic verse is also usually anonymous. Where possible examples of each poet's surviving work is presented at Welsh Poetry at Wikisource

Each period of the poets listed below is accompanied by a graphical timeline to illustrate the main events and individuals that influenced the poets and their work. These timelines also depict the development of the Welsh language. Further details of its development may be found at Welsh language. Pre 6th century 

No works by Welsh poets prior to the 6th century have survived. Tradition records:

Maelgwyn of Llandaff (c. 450) – said, according to one source, to have written of Joseph of Arimathea's burial at Glastonbury. However, in the mid-5th century he would have spoken Brythonic, not Welsh, and as a monk would probably have written in Latin. His existence is doubtful. St. Meugan (fl. c. late 5th century) – possibly a court poet to Cadwallon of Gwynedd

6th century to 1100

Extant

The bulk of surviving verse from the period known as "Canu'r Bwlch" is anonymous. (see Wikisource)

The works of the following poets, belonging to the Hengerdd or Cynfeirdd period, are extant and accepted as probably genuine:

Aneirin (Neirin mab Dwyrei) (fl. 550–600)
Taliesin (fl. later 6th century)

The following works are probably apocryphal:

Meigant (fl. c. 600–620) – a poet whose surviving work is recorded in the  Black Book Of Carmarthen. Afan Ferddig (7th century) – accepted as the author of Moliant Cadwallon a praise poem to Cadwallon ap Cadfan
Juvencus Manuscript/ Cambridge Juvencus (late 9th century) contains two Welsh englyn-poems, one of nine and one of three englynion. For the text and Sir Ifor William's translation see: The Juvencus Englynion. The englyn-cycles which were previously attributed to Llywarch Hen and Heledd are now seen as works of later (9th–10th century) poets. St Elaeth (11th century) – a poet and a monk whose surviving verse is recorded in the Black Book Of Carmarthen. Non-extant or doubtful 

Four others are named by Nennius as poets of renown alongside Taliesin and Aneirin:
Blwchbardd
Cian (Guenith Guaut)
Culfardd
Talhaearn Tad Awen

Arofan (7th century)
 (?9th century) – referred to in several poems but otherwise unknown. None of his work survives. The earliest reference to him is in a text  (English version) found in the Black Book Of Carmarthen. However, a later charter of Sir Nicholas FitzMartin, Marcher Lord of Kemes, off-handedly describes someone as his descendant; the charter grants the supposed descendant land in the Preseli Hills. Bleheris (?11th century) – an otherwise unknown poet of doubtful authenticity referred to as "born and bred in Wales" in Gawain and as a source for the story. Other 
Myrddin ab Morfryn – was believed by some to be an historical person who died in AD 570, but is now accepted as a mythical figure (see Merlin). Timeline

1290 to c.1500 
The poets of this period are known as Beirdd yr Uchelwyr. The list is fairly chronological but not exhaustive as the work of some minor poets of the late 15th and 16th centuries remains in manuscript and a large corpus of late medieval Darogan, prophetic verse, is anonymous or attributed to early poets. Traditional patronage dwindled in the late 16th century but a handful of bards still received patronage from the gentry into the 17th century. Free verse by individuals composing "freelance" gradually took over from the mid-16th century onwards. Casnodyn (fl. first half of the 14th century)
