Magi, a religious sect among the eastern nations of the world, and particularly in Persia. They had great influence in the political as well as religious affairs of the state, and a monarch seldom ascended the throne without their previous approbation. Zoroaster was founder of their sect. They paid particular homage to fire, which they deemed a deity, as pure in itself, and the purifier of all things. In their religious tenets they had two principles, one good, the source of everything good; and the other evil, from whence sprang all manner of ills. Their professional skill in the mathematics and philosophy rendered everything familiar to them, and from their knowledge of the phenomena of the heavens, the word Magi was applied to all learned men; and in process of time, the Magi, from their experience and profession, were confounded with the magicians who impose upon the superstitious and credulous. Hence the word Magi and Magicians became synonymous among the vulgar. Smerdis, one of the Magi, usurped the crown of Persia after the death of Cambyses, and the fraud was not discovered till the seven noble Persians conspired against the usurper, and elected Darius king. From this circumstance there was a certain day on which none of the Magi were permitted to appear in public, as the populace had the privilege of murdering whomsoever of them they met.

Magna Mater, a name given to Cybele.

Magnentius, an ambitious Roman, who distinguished himself by his cruelty and perfidy. He conspired against the life of Constans, and murdered him in his bed. This cruelty was highly resented by Constantius; and the assassin, unable to escape from the fury of his antagonist, murdered his own mother and the rest of his relations, and afterwards killed himself by falling upon a sword, which he had thrust against a wall. He was the first of the followers of christianity who ever murdered his lawful sovereign, A.D. 353.

Magnes, a young man who found himself detained by the iron nails which were under his shoes as he walked over a stone mine. This was no other than the magnet, which received its name from the person who had been first sensible of its powers. Some say that Magnes was a slave of Medea, whom that enchantress changed into a magnet. Orphic Lithica, bk. 10, li. 7.——A son of Æolus and Anaretta, who married Nais, by whom he had Pierus, &c. Apollodorus, bk. 1, ch. 7.——A poet and musician of Smyrna, in the age of Gyges king of Lydia.

Magnēsia, a town of Asia Minor on the Mæander, about 15 miles from Ephesus, now called Guzelhizar. It is celebrated for the death of Themistocles, and for a battle which was fought there 187 years before the christian era, between the Romans and Antiochus king of Syria. The forces of Antiochus amounted to 70,000 men, according to Appian, or 70,000 foot and 12,000 horse, according to Livy, which have been exaggerated by [♦]Florus to 300,000 men; the Roman army consisted of about 28,000 or 30,000 men, 2000 of which were employed in guarding the camp. The Syrians lost 50,000 foot and 4000 horse, and the Romans only 300 killed, with 25 horse. It was founded by a colony from Magnesia in Thessaly, and was commonly called Magnesia ad Mæandrum, to distinguish it from another called Magnesia ad Sipylum in Lydia, at the foot of mount Sipylus. This last was destroyed by an earthquake in the reign of Tiberius.——A country on the eastern parts of Thessaly, at the south of Ossa. It was sometimes called Æmonia and Magnes Campus. The capital was also called Magnesia.——A promontory of Magnesia in Thessaly. Livy, bk. 37.—Florus, bk. 2.—Appian.

Mago, a Carthaginian general sent against Dionysius tyrant of Sicily. He obtained a victory, and granted peace to the conquered. In a battle which soon after followed this treaty of peace, Mago was killed. His son, of the same name, succeeded to the command of the Carthaginian army, but he disgraced himself by flying at the approach of Timoleon, who had come to assist the Syracusans. He was accused in the Carthaginian senate, and he prevented by suicide the execution of the sentence justly pronounced against him. His body was hung on a gibbet, and exposed to public ignominy.——A brother of Annibal the Great. He was present at the battle of Cannæ, and was deputed by his brother to carry to Carthage the news of the celebrated victory which had been obtained over the Roman armies. His arrival at Carthage was unexpected, and more powerfully to astonish his countrymen on account of the victory of Cannæ, he emptied in the senate-house the three bushels of golden rings which had been taken from the Roman knights slain in battle. He was afterwards sent to Spain, where he defeated the two Scipios, and was himself, in another engagement, totally ruined. He retired to the Baleares, which he conquered; and one of the cities there still bears his name, and is called Portus Magonis, Port Mahon. After this he landed in Italy with an army, and took possession of part of Insubria. He was defeated in a battle by Quintilius Varus, and died of a mortal wound 203 years before the christian era. Livy, bk. 30, &c. Cornelius Nepos, Hannibal, ch. 8, gives a very different account of his death, and says he either perished in a shipwreck, or was murdered by his servants. Perhaps Annibal had two brothers of that name.——A Carthaginian, more known by the excellence of his writings than by his military exploits. He wrote 28 volumes upon husbandry; these were preserved by Scipio, at the taking of Carthage, and presented to the Roman senate. They were translated into Greek by Cassius Dionysius of Utica, and into Latin by order of the Roman senate, though Cato had already written so copiously upon the subject; and the Romans, as it has been observed, consulted the writings of Mago with greater earnestness than the books of the Sybilline verses. Columella.——A Carthaginian sent by his countrymen to assist the Romans against Pyrrhus and the Tarentines, with a fleet of 120 sail. This offer was politely refused by the Roman senate.
