Neptu´nus. One of the gods, son of Saturn and Ops, and brother to Jupiter and Pluto. He was devoured by his father as soon as he was born, and restored to life again by a potion given to Saturn, by Metis, the first wife of Jupiter. Neptune shared with his brothers the empire of Saturn, and received as his portion the kingdom of the sea. He did not think this equivalent to the empire of heaven and earth, which Jupiter had claimed, therefore he conspired to dethrone him. The conspiracy was discovered, and Jupiter condemned Neptune to build the walls of Troy. He married Amphitrite, who thus broke a vow she had made of perpetual celibacy.

Ne´ro, Clau´dius Domit´ius Cæ´sar. A celebrated Roman emperor, son of Caius Domitius Ahenobarbus and Agrippina, the daughter of Germanicus. His name is the synonym for cruelty and vice. In the night it was his wont to sally out from his palace to visit the meanest taverns and the different scenes of depravity that were to be found. He appeared on the stage, sometimes representing the meanest characters. He resolved to imitate the burning of Troy, and caused Rome to be set on fire in different places, the flames being unextinguished for nine days, and he enjoyed the terrible scene. During the conflagration he placed himself on the top of a tower and sang, accompanying himself on a lyre, of the destruction of Troy. Many conspiracies were formed against him, the most dangerous of which he was saved from by the confession of a slave. He killed himself A.D. 68, in the thirty-second year of his age, after a reign of thirteen years and eight months. Wretch that he was, it is said that he had some few to mourn for him, and Suetonius records that some unseen hand had placed flowers on his tomb.
