Welsh bard
Taliesin (or Taliessin; c. 534 – c. 599) is the earliest poet in any Brittonic language whose work has survived. Although he probably composed in Cumbric, since the songs most surely attributed to him are praise poems to Urien Rheged, a warrior monarch of the Old North, these poems survive in Middle Welsh in the so-called Book of Taliesin, written down around the 13th century, along with about forty more of more dubious attribution. His name means "Radiant Brow" (tal iesin in Welsh). The book was translated by Robert Williams and published in The Four Ancient Books of Wales (1858) by W. F. Skene. These translations are notoriously unreliable, but few better have since appeared, due to the obscurity and compression of the verse.

The rock wave-surrounded, by great arrangement, Will convey for us a defence, a protection from the enemy. The rock of the chief proprietor, the head of tranquillity. The intoxication of meads will cause us to speak. I am a cell, I am a cleft, I am a restoration, I am the depository of song; I am a literary man; I love the high trees, that afford a protection above, And a bard that composes, without earning anger; I love not him that causes contention; He that speaks ill of the skilful shall not possess mead.
I am a harmonious one; I am a clear singer. I am steel; I am a druid. I am an artificer; I am a scientific one. I am a serpent; I am love; I will indulge in feasting. I am not a confused bard drivelling, When songsters sing a song by memory, They will not make wonderful cries; May I be receiving them. Like receiving clothes without a hand, Like sinking in a lake without swimming The stream boldly rises tumultuously in degree.
The number that have been, and will be, Above heaven, below heaven, how many there are. And as many as have believed in revelation, Believed through the will of the Lord. As many as are on wrath through the circles, Have mercy, God, on thy kindred. May I be meek, the turbulent Ruler, May I not endure, before I am without motion. Grievously complaineth every lost one, Hastily claimeth every needy one.
