Much of the earliest Welsh literature was actually composed in or near the country we now call Scotland, in the Brythonic speech, from which Welsh would be derived, which was not then confined to Wales and Cornwall, although it was only written down in Wales much later. These include "The Gododdin", considered the earliest surviving verse from Scotland, which is attributed to the bard Aneirin, said to have been resident in Brythonic kingdom of Gododdin in the sixth century. It is a series of elegies to the men of the Gododdin killed fighting at the "Battle of Catraeth" around 600 AD. Similarly, the "Battle of Gwen Ystrad" is attributed to Taliesin, traditionally thought to be a bard at the court of Rheged in roughly the same period.
