relations between mark antony and cleopatra perhaps soured when he not only married octavia, but having moved his headquarters to athens also sired her two children, antonia the elder in 39 bc and antonia minor in 36 bc. however, cleopatra's position in egypt was secure. her rival herod was occupied with civil war in judea that required heavy roman military assistance, but received none from cleopatra. since the triumviral authority of mark antony and octavian had expired on 1 january 37 bc, octavia arranged for a meeting at tarentum where the triumvirate was officially extended to 33 bc. with two legions granted by octavian and a thousand soldiers lent by octavia, mark antony traveled to antioch, where he made preparations for war against the parthians.
