There is very little to say about the poem of The Horse, the Goose, and the Sheep (published c.1477), by William Caxton, in terms of its sole reference to bees. The poem was written by John Lydgate (c. 1370-c.1451), who by this time was dead some twenty-five years.
The reference to bees is one in a long list referencing the correct terminology for a group of something, in this instance, ‘a swarm of bees’, which fits into the list alongside:
A Gagyll of women
A Chyrme of fynches
A Swarme of bees
A Exaltacion of larkes
A disce[n]cion of wodewalis
And so on. The short pamphlet was possibly printed twice by William Caxton and then reprinted by Wynkyn de Worde in 1495, 1499 and 1500. However, the editions by Wynkyn de Worde did not contain the reference to bees, having cut down the list of correct terminology to a smaller length. According to Curt F. Buhler the poem appears to have been popular for a short time with several manuscript versions also surviving.
