This is a 1735 fourth ed. of the three-act ballad opera "The beggar's opera" by John Christopher Pepusch and John Gay. It includes the score for the overture (for violins (2), viola, and bass ensemble) and the melodies of each song. The inscription, "Nos haec novimus esse nihil" (transl. as, We know these to be nothing) that appears on the t.p. is an epigram by Marcus Valerius Martialis from his Books of Epigrams. On the back of the t.p. appears the advertisement of these works printed by John Watts: Fifty one new fables in verse; The tunes to the songs in the Beggar's Opera, transposed for the flute; and Gay's opera "Achilles." A table of songs shows the first lines of text for each act. The item includes a list of characters.
