A source for Shakespeare's sub-plot 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.  An additional minor source is Mostellaria by Plautus , from which Shakespeare probably took the names of Tranio and Grumio. 
Before they had the vote, they had a voice. Renowned for her thoroughly original and theatrical approach to Shakespeare, Artistic Director Barbara Gaines now brings audiences a witty, thought-provoking debate on power, politics, and love. The year is 1919. Amidst suffrage marches, members of a Chicago women’s club convene to rehearse their upcoming production of The Taming of the Shrew . Along the way, they both perform Shakespeare’s play and re-examine the characters’ status in society—as well as their own. Longtime Second City writer Ron West has penned additional dialogue to help set the scene in the uniquely personal setting of CST’s Courtyard Theater, as the women fight through adversity to present their own perspective on Katherine and Petruchio’s raucous courtship.
