TARQUINIUS SUPERBUS was Rome's last king and ruled 534-510 B.C. His son Sextus raped Lucretia, wife of his nephew Tarquinius Collatinus, a deed that led to an insurrection, during which the people drove the Tarquins from Rome (Livy, Ab urbe condita liber I.57-59; Ovid, Fasti II.685-852).
The narrator says that he will tell of the exiling of kings and of the last king of Rome, as told by Ovid and Titus Livy, LGW 1680-1683. [Colatyn: Lucrece: Tarquinius]
The name appears in final rhyming position, LGW 1682. Tarquinius is the adjective of Tarquinii, the Etruscan town from which the Tarquins came.
