A source for Shakespeare's subplot was first identified by Alfred Tolman in 1890 as Ludovico Ariosto's I Suppositi, which was published in 1551. George Gascoigne's English prose translation Supposes was performed in 1566 and printed in 1573. In I Suppositi, Erostrato (the equivalent of Lucentio) falls in love with Polynesta (Bianca), daughter of Damon (Baptista). Erostrato disguises himself as Dulipo (Tranio), a servant, whilst the real Dulipo pretends to be Erostrato. Having done this, Erostrato is hired as a tutor for Polynesta. Meanwhile, Dulipo pretends to formally woo Polynesta so as to frustrate the wooing of the aged Cleander (Gremio). Dulipo outbids Cleander, but he promises far more than he can deliver, so he and Erostrato dupe a travelling gentleman from Siena into pretending to be Erostrato's father, Philogano (Vincentio). However, when Polynesta is found to be pregnant, Damon has Dulipo imprisoned (the real father is Erostrato). Soon thereafter, the real Philogano arrives, and all comes to a head. Erostrato reveals himself, and begs clemency for Dulipo. Damon realises that Polynesta is truly in love with Erostrato, and so forgives the subterfuge. Having been released from jail, Dulipo then discovers he is Cleander's son.For more information on the relationship between Supposes and The Shrew, see . An additional minor source is Mostellaria by Plautus, from which Shakespeare probably took the names of Tranio and Grumio.
