The text below is a fine poem describing the specific foods and drinks ingested on the four Celtic feasts. The poem is preserved in two manuscripts: Bodleian codex Rawlinson B. 512, folio 98b, 2 and in the British Museum MS. Harleian 5280, folio 35b, 2, written in the 16th c. by Gilla Riabach O’Clery, and edited and translated by Kuno Meyer in 1894. In his introduction, Meyer demonstrates that both transcripts are derived from one common source.2502 From the character of the Old-Irish forms, he deduces that the poem goes back to an original composed in the 8th c.
The four Celtic feasts are: Beltaine (May 1st ), which now corresponds to May-Day; Lugnasad (1st Sunday of August), which is now Lammas-Day; Samhain (November 1st), which celebrates the end of summer and the return to cold and darkness, and is now Halloween; and Imbolc (February 1st), which has been replaced by the feast of St Brigit (Candlemas). In the Celtic world, the day begins with the onset of darkness, and thus each of these festivals begins their celebration on the night before the actual (modern) date.
