A celebrated Roman lady, daughter of Lucretius and wife of Tarquinius Collatinus. A number of young noble Romans at Ardea, among whom were Collatinus and the sons of Tarquin the Proud, were discussing the virtues of their wives at home, and it was agreed to go to Rome to ascertain how their wives employed themselves in their husbands' absence in the camp. While the wives of the others were indulging in feasting and dissipation, Lucretia was found in her house employing herself with her servants in domestic duties. She was brutally treated by Sextus Tarquin, a relative of Collatinus, and stabbed herself. This was the signal for a rebellion, the result being the expulsion of the Tarquins from Rome. Lucretius, Carus T. A celebrated Roman poet and philosopher. The tenets of Epicurus were embraced by him, and were explained and elucidated in a poem which he wrote, De Rerum Naturâ. This poem is distinguished by genius and elegance, but the doctrines it inculcates have an atheistical tendency. Lucretius is said to have destroyed himself B. c. 54. Lucullus, Lucius Licinius . A Roman noted for his fondness of luxury and for his military abilities. He was born about 115 years before the Christian era, and distinguished himself by his proficiency in eloquence and philosophy. He was soon advanced to the consulship, and intrusted with the management of the Mithridatic war, in which he displayed his military talents. 2026 Editor's Note: The account of Lucretia is considered part of Roman mythohistory, as there are no contemporary sources for the events described. While the narrative attributes the fall of the monarchy to her suicide, modern historians note that accounts of the incident were first recorded by writers like Livy approximately 500 years after the fact.
