Aneirin was a late 6th or early 7th century Brythonic poet from the Hen Ogledd, the Cumbric-speaking regions of northern Britain. His poem Y Gododdin, an elegy for those British warriors who fell in the disastrous battle of Cattraeth, survives only in a late, corrupt and heavily interpolated version.
Aneirin Stanza A8, pp. 118. "This famous quotation does not mean that the Gododdin army was too drunk to fight properly, but that they lost their lives in 'earning their mead'" (Jackson The Gododdin p. 35).
