 In the quarto, Chapman dedicated the play to Sir Thomas Walsingham.Chapman's verse dedication specifies that earlier texts of Chapman plays had been issued "without my passport, patch'd with others' wit..." Chapman refers here to the defective texts of his earliest extant plays, "The Blind Beggar of Alexandria" (1596; printed 1598) and "An Humorous Day's Mirth" (1597; printed 1599).Chapman based the plot of "All Fools" on two classical Roman comedies by Terence, the "Heauton Timorumenos" and the "Adelphoe".
