The Book of Taliesin (Welsh: Llyfr Taliesin) is one of the most famous of Middle Welsh manuscripts, dating from the first half of the 14th century though many of the fifty-six poems it preserves are taken to originate in the 10th century or before.

The volume contains some of the oldest poems in Welsh, possibly but not certainly dating back to the sixth century and to a real poet called Taliesin (though these, if genuine, would have been composed in the Cumbric dialect of Brittonic-speaking early medieval north Britain, being adapted to the Welsh dialect of Brittonic in the course of their transmission in Wales).

The manuscript, known as Peniarth MS 2 and kept at the National Library of Wales, is incomplete, having lost a number of its original leaves including the first. It was named Llyfr Taliessin in the seventeenth century by Edward Lhuyd and hence is known in English as "The Book of Taliesin". The palaeographer John Gwenogvryn Evans dated the Book of Taliesin to around 1275, but Daniel Huws dated it to the first quarter of the fourteenth century, and the fourteenth-century dating is generally accepted.^[1]: 164

The Book of Taliesin was one of the collection of manuscripts amassed at the mansion of Hengwrt, near Dolgellau, Gwynedd, by the Welsh antiquary Robert Vaughan (c. 1592–1667); the collection was eventually donated by Sir John Williams in 1907 to the newly established National Library of Wales as the Peniarth or Hengwrt-Peniarth Manuscripts.^[2]

It appears that some "marks", presumably awarded for poems, measuring their "value", are extant in the margin of the Book of Taliesin.

Many of the poems have been dated to the twelfth and thirteenth centuries and are likely to be the work of poets adopting the Taliesin persona for the purposes of writing about awen (poetic inspiration), characterised by material such as:

I have been a multitude of shapes,

Before I assumed a consistent form.

I have been a sword, narrow, variegated,

I have been a tear in the air,

I have been in the dullest of stars.

I have been a word among letters,

I have been a book in the origin.

A few are attributed internally to other poets. A full discussion of the provenance of each poem is included in the definitive editions of the book's contents poems by Marged Haycock.^{[3][page needed][4][page needed]}

The scholar Amy Mulligan states that only twelve of the poems, called the Canu Taliesin (song of Taliesin), mainly in praise of Urien, sixth century ruler of Rheged, "are accepted as canonical poems by a historical Taliesin".^[5] Ifor Williams similarly describes the Canu Taliesin as credibly being the work of Taliesin, or at least 'to be contemporary with Cynan Garwyn, Urien, his son Owain, and Gwallawg', possibly historical kings who respectively ruled Powys; Rheged, which was centred in the region of the Solway Firth on the borders of present-day England and Scotland and stretched east to Catraeth (identified by most scholars as present-day Catterick in North Yorkshire) and west to Galloway; and Elmet.^[6] These are (giving Skene's numbering used in the content list below in Roman numerals, the numbering of Evans's edition of the manuscript in Arabic, and the numbers and titles of Williams's edition in brackets):

Poems 2, 3, 4, 5, 6, 8, and 9 (in Williams's numbering) close with the same words, suggesting common authorship, while 4 and 8 contain internal attributions to Taliesin. The closing tag runs

The precise dating of these poems remains uncertain. Re-examining the linguistic evidence for their early date, Patrick Sims-Williams concluded in 2016 that

evaluating the supposed proofs that poems in the Books of Aneirin and Taliesin cannot go back to the sixth century, we have found them either to be incorrect or to apply to only a very few lines or stanzas that may be explained as additions. It seems impossible to prove, however, that any poem must go back to the sixth century linguistically and cannot be a century or more later.^[1]: 217

Scholarly English translations of all these are available in Poems from the book of Taliesin (1912) and the modern anthology The Triumph Tree.^[8]

Among probably less archaic but still early texts, the manuscript also preserves a few hymns, a small collection of elegies to famous men such as Cunedda and Dylan Eil Ton and also famous enigmatic poems such as The Battle of Trees, The Spoils of Annwfn (in which the poet claims to have sailed to another world with Arthur and his warriors), and the tenth-century prophetic poem Armes Prydein Vawr. Several of these contain internal claims to be the work of Taliesin, but cannot be associated with the putative historical figure.

Many poems in the collection allude to Christian and Latin texts as well as native British tradition, and the book contains the earliest mention in any Western post-classical vernacular literature of the feats of Hercules and Alexander the Great.

The introduction to Gwyneth Lewis and Rowan Williams's translation of The Book of Taliesin suggests that later Welsh writers came to see Taliesin as a sort of shamanic figure. The poetry ascribed to him in this collection shows how he can not only channel other entities himself (such as the Awen) in these poems, but that the authors of these poems can in turn channel Taliesin as they both create and perform the poems that they ascribe to Taliesin's persona. This creates a collectivist, rather than individualistic, sense of identity; no human is simply one human, humans are part of nature (rather than opposed to it), and all things in the cosmos can ultimately be seen to be connected through the creative spirit of the Awen. ^[9]
