Sextus Tarquinius was one of the sons of the last king of Rome, Lucius Tarquinius Superbus. In the original account of the Tarquin dynasty presented by Fabius Pictor, he is the second son, between Titus and Arruns.[1] However, according to Livy and Dionysius of Halicarnassus, he was either the third or first son, respectively.[2] According to Roman tradition, his rape of Lucretia was the precipitating event in the overthrow of the monarchy and the establishment of the Roman Republic.
