or the Smoking Mountain, as its name imports in Mexican, an active volcano of Mexico, in the state of La Puebla, 35 miles S.W. of the town of that name. It is cone-shaped, and rises to the height of 17,793 feet above the sea. From its base up to the height of 12,700 feet, it is covered with forests; but above that the mountain is quite bare, its sides being strewn with pumice, sand, and ashes, from the crater, and generally covered with snow. The crater is about a mile in diameter, and 1000 feet deep. Good sulphur may be obtained from it.

POPPÆA, SABINA, a Roman matron, daughter of Titus Ollius, and grand-daughter of Poppeus Sabinius, who had been consul in A.D. 9. She was married and had a son to Rufius Crispinus, a Roman knight. Her beauty captivated Otho, one of Nero's favourites, who carried her off and married her; but he was not long permitted to retain her, for Nero, having heard her extolled for her accomplishments, sent Otho out of Italy under pretence of presiding over one of the Roman provinces, shortly after which Nero murdered his mother, and subsequently his wife Octavia, and married Poppea; but she did not long enjoy the imperial dignity, for Nero soon began to despise her, and treat her with great barbarity. She bore him a son; and when she was again far advanced in pregnancy, he is said to have kicked her, of which she died, about 65 A.D. It is said she was so anxious to preserve her beauty that 500 she-asses were milked, in which she used daily to bathe.
