This article concerns two seventeenth-century poems that have not been printed before except for brief extracts. They occupy pages 26–36 in a commonplace book in the Folger Shakespeare Library, Washington, D. C., known as MS.V.a.160 (formerly MS.452.1). The poems are there attributed to Thomas Dekker, one of the better-known Jacobean dramatists, author of The Shoemakers' Holiday and other middle-class comedies, and of a large number of pamphlets of ‘London life’ which are of great interest to the student of colloquial speech in the Jacobean period. Though the commonplace book includes other interesting material, my discussion will confine itself to the two Dekker items, their import and their claim to genuineness, with one slight exception only. The exception is a version of a little-known epitaph attributed, though not very persuasively, to Shakespeare, which I cite in a footnote since it has apparently not been printed for over a hundred years. Of the two Dekker poems, the second one is a bawdy song which probably refers to a special popular entertainment of the day.
