"The Boke of Phyllyp Sparowe," the lament of Jane Scroop, a schoolgirl in the Benedictine convent of Carrow near Norwich, for her dead bird, was no doubt inspired by Catullus. It is a poem of some 1,400 lines and takes many liberties with the formularies of the church. The digressions are considerable. It depicts Jane as having a wide reading in the romances of Charlemagne, of the Round Table, "The Four Sons of Aymon" and the ""Trojan cycle."" Skelton finds space to give an opinion of Geoffrey Chaucer, John Gower and John Lydgate. Whether we can equate this opinion, voiced by the character of Jane, with Skelton's own is contentious. It would appear that he seems to have realised Chaucer's value as a master of the English language. Gower's matter was, Jane tells us, "worth gold," but his English she regards as antiquated. The verse in which the poem is written, called from its inventor "Skeltonical," is here turned entirely to whimsical use. The lines are usually six-syllabled but vary in length, and rhyme in groups of two, three, four and even more. It is not far removed from the old alliterative English verse, and well fitted to be chanted by the minstrels who had sung the old ballads. For its comic admixture of Latin Skelton had abundant example in French and Low Latin macaronic verse. He makes frequent use of Latin and French words to carry out his exacting system of frequently recurring rhymes. This breathless, voluble measure was in Skelton's energetic hands an admirable vehicle for invective, but it easily degenerated into doggerel.
