explanation (razo):

This poem is based off of Song 49 in the Carmina Cantabrigiensia (the "songs of Cambridge"), a collection of eleventh-century songs and poems probably from Germany (the manuscript title refers to Cambridge because it was named so by modern scholars, as the manuscript was discovered in a monastic library in Cambridge). The original poem is a celebration of the narrator's sexual prowess; I thought it would be rather hilarious to twist the idea around and celebrate the narrator's lack of sexual ability and endurance (or perhaps celebrating the superhuman ability of his beloved!). Each verse line is 7 syllables long, with an "et a et o" refrain, then a rhyming line of 7 syllables, then the longer "et a et o et a et o" refrain, with 4 rhyming verses in total. The third verse of the original is incomprehensible - the source I used, which is fairly thorough, provides guesses at some letters and ellipses for those which are completely unreadable. However, this was no real obstacle to understanding the poem's meter or intent.
