=Liv´ius Androni´cus= was a dramatic poet who flourished at Rome about 240 years before the Christian era. =Longi´nus, Dionys´ius Cas´sius.= A celebrated Greek philosopher of Athens. He was preceptor of the Greek language, and afterwards minister, to Zenobia, the famous queen of Palmyra. =Luca´nus M. Annæ´us.= A native of Corduba in Spain. At an early age he went to Rome, where his rising talents recommended him to the emperor Nero. He unwisely entered into a poetical contest with Nero, in which he obtained an easy victory, which greatly offended the emperor. After this Lucan was exposed to much annoyance from Nero, and was induced to join in a conspiracy against him, on which he was condemned to death, the mode of which he had the liberty of choosing. He decided to have his veins opened in a warm bath, and died quoting some lines from his "Pharsalia." Of all his works none but the "Pharsalia" remains. =Lucia´nus.= A celebrated writer of Samosata. His works are numerous, consisting chiefly of dialogues written with much force. He died A.D. 180, being, as some say, torn in pieces by dogs for his impiety. =Lu´cifer.= The name of the planet Venus, or morning star. It is called Lucifer when appearing in the morning before the sun, but when it appears after its setting it is called Hesperus. =Lucil´ius, C.= A Roman knight, who is regarded as the first satirical writer amongst the Romans. Of thirty satires which he wrote only a few verses remain. He died at Naples B.C. 103. =Lucil´ius Luci´nus.= A famous Roman who fled with Brutus from the battle of Philippi. He was taken prisoner, but the conquerors spared his life. =Luci´na.= Daughter of Jupiter and Juno. She was the goddess who presided over the birth of children. =Lucre´tia.= 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. =Lucre´tius, Ca´rus 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 natura_. 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.
