Richard Chamberlain, b. 31 March 1934Giacomo Casanova (b. April 2, 1725) is an Aries archtype, the priapic libertine, irrepresible autobiographer, soldier, charlatan and adventurer, who once robbed a grave as a practical joke. Among his escapades his literal escape from the Venetian prison stands out as a dramatization of the Aries birth experience. He also stole and sold the secret formula of the red dye of British military cloth. Aries actors have often been cast as Casanova: David Tennant, Heath Ledger, Richard Chamberlain, while the not-Aries Donald Sutherland was distinctively miscast in Fellini's Casanova. Two other Aries natives are highpoints in the history of promiscuity: the Italian pornographer Pietro Aretino, (notably rendered in Titian red) 
Pietro Aretino (b. 20 April 1492) by Titian;)
John Wilmot, Lord Rochester (b.1 April 1647)and the English poet-rake Lord Rochester. Closer to home, Aries actors Marlon Brando and Warren Beatty have famously notched bedposts.
