sinistra: as the right hand was given in token of friendship, the left was proverbially the one devoted to theft; cf. Pl. Pers. 227 “illa altera furtifica laeva” ; Ov. Met. 13.111 “[nec clipeus] conveniet natae ad furta sinistrae:” the word occurs in Catul. 47.1 in the figurative sense of ‘accomplices’ in thieving.
