The teachings of Anchises to Æneas, respecting the nature of the human soul, were in conformity with the doctrines of the Pythagoreans. Pythagoras (born about 540 B.C.) was a native of the island of Samos, but passed the chief portion of his life at Crotona in Italy. He is therefore sometimes called "the Samian," and sometimes "the philosopher of Crotona." When young he traveled extensively and is said to have visited Egypt, where he was instructed by the priests, and afterwards to have journeyed to the East, where he visited the Persian and Chaldean Magi, and the Brahmins of India. He established himself at Crotona, and enjoined sobriety, temperance, simplicity, and silence upon his throngs of disciples. Ipse dixit (Pythagoras said so) was to be held by them as sufficient proof of anything. Only advanced pupils might question. Pythagoras considered numbers as the essence and principle of all things, and attributed to them a real and distinct existence; so that, in his view, they were the elements out of which the universe was constructed.

As the numbers proceed from the monad or unit, so he regarded the pure and simple essence of the Deity as the source of all the forms of nature. Gods, demons, and heroes are emanations of the Supreme, and there is a fourth emanation, the human soul. This is immortal, and when freed from the fetters of the body, passes to the habitation of the dead, where it remains till it returns to the world, to dwell in some other human or animal body; at last, when sufficiently purified, it returns to the source from which it proceeded. This doctrine of the transmigration of souls (metempsychosis), which was originally Egyptian and connected with the doctrine of reward and punishment of human actions, was the chief reason why the Pythagoreans killed no animals. Ovid represents Pythagoras saying that in the time of the Trojan War he was Euphorbus, the son of Panthus, and fell by the spear of Menelaüs. Lately, he said, he had recognized his shield hanging among the trophies in the Temple of Juno at Argos.

On Metempsychosis, see the essay in the Spectator (No. 343) on the Transmigration of Souls; Shakespeare, Merchant of Venice (Gratiano to Shylock).

Harmony of the Spheres. The relation of the notes of the musical scale to numbers, whereby harmony results from proportional vibrations of sound, and discord from the reverse, led Pythagoras to apply the word harmony to the visible creation, meaning by it the just adaptation of parts to each other. This is the idea which Dryden expresses in the beginning of his song for St. Cecilia's Day, "From harmony, from heavenly harmony, This everlasting frame began."

In the center of the universe (as Pythagoras taught) there was a central fire, the principle of life. The central fire was surrounded by the earth, the moon, the sun, and the five planets. The distances of the various heavenly bodies from one another were conceived to correspond to the proportions of the musical scale. See Merchant of Venice, Act V (Lorenzo and Jessica), for the Music of the Spheres; also Milton, Hymn on the Nativity. See Longfellow's Verses to a Child, and Occultation of Orion, for Pythagoras as inventor of the lyre.

260. Camilla. Pope, illustrating the rule that "the sound should be an echo to the sense," says:

When Ajax strives some rock's vast weight to throw,
The line, too, labors and the words move slow;
Not so when swift Camilla scours the plain,
Flies o'er th' unbending corn, or skims along the main.

268-281. On Norse mythology, see R. B. Anderson, Norse Mythology, or the Religion of our Forefathers (Chicago, 1875); Anderson, Horn's Scandinavian Literature (Chicago, S. C. Griggs & Co., 1884); Dasent, Popular Tales from the Norse (transl. from P. C. Asbjörnsen, New York, 1859); Thorpe's translation of Sæmund's Edda, 2 vols. (London, 1866); Icelandic Poetry or Edda of Sæmund, transl. into English verse (Bristol, A. S. Cottle, 1797); Augusta Larned, Tales from the Norse Grandmother (New York, 1881); H. W. Mabie, Norse Stories (Boston, 1882). A critical edition of the Elder Edda is Sophus Bugge's (Christiania, 1867). The Younger Edda: Edda Snorra Sturlasonar, 2 vols. (Hafniae, 1848-1852); by Thorleif Jonsson (Copenhagen, 1875); Translation: Anderson's Younger Edda (Chicago, S. C. Griggs & Co., 1880) (see references at foot of pp. 458-461 and in C. 282). Illustrative poems: Gray, Ode on the Descent of Odin, Ode on the Fatal Sisters; Matthew Arnold, Balder Dead; Longfellow, Tegnér's Drapa, on Balder's Death; William Morris, The Funeral of Balder, in The Lovers of Gudrun (Earthly Paradise); Robert Buchanan, Balder the Beautiful; W. M. W. Call, Balder; and Thor. Sydney Dobell's Balder does not rehearse the Norse myth. It is a poem dealing with the spiritual maladies of the time, excellent in parts, but confused and uneven. Longfellow's Saga of King Olaf (the Musician's Tale, Wayside Inn) is from the Heimskriṅgla, or Book of Stories of the Kings, edited by Snorri Sturlason. Many of the cantos of the Saga throw light on Norse mythology. See also the Hon. Roden Noël's Ragnarok (in the Modern Faust), for an ethical modification of the ancient theme.

Anses (the Asa-folk, Æsir, etc.). The word probably means ghost, ancestral spirit,—of such kind as the Manes of the Romans. The derivation may be from the root AN, 'to breathe,' whence animus (Vigfusson and Powell, Corp. Poet. Bor. 1, 515). According to Jordanes, the Anses were demigods, ancestors of royal races. The main cult of the older religion was ancestor-worship, Thor and Woden being worshiped by a tribe, but each family having its own anses, or deified ancestors (Corp. Poet. Bor. 2, 413). Elf was another name used of spirits of the dead. Later it sinks to the significance of "fairy." Indeed, say Vigfusson and Powell, half our ideas about fairies are derived from the heathen beliefs as to the spirits of the dead, their purity, kindliness, homes in hillocks (cf. the Irish "folk of the hills," Banshees, etc.) (Corp. Poet. Bor. 2, 418).
