period which preceded and coincided with the time of Homer.

Pindar (b.c. 522-442) is the first writer of antiquity who has described Etna. In the first of the Pythian Odes for Hieron, of the town of Aitna, winner in the chariot race in b.c. 474, he exclaims:

. . . "He (Typhon) is fast bound by a pillar of the sky, even by snowy Etna, nursing the whole year's length her dazzling snow. Whereout pure springs of unapproachable fire are vomited from the inmost depths: in the daytime the lava-streams pour forth a lurid rush of smoke; but in the darkness a red rolling flame sweepeth rocks with uproar to the wide deep sea . . . That dragon-thing (Typhon) it is that maketh issue from beneath the terrible fiery flood."[1]

Æschylus (b.c. 525-456) speaks also of the "mighty Typhon," (Prometheus V.):

. . . . . "He lies
A helpless, powerless carcase, near the strait
Of the great sea, fast pressed beneath the roots
Of ancient Etna, where on highest peak
Hephæstos sits and smites his iron red hot,
From whence hereafter streams of fire shall burst,
Devouring with fierce jaws the golden plains
Of fruitful, fair Sikelia."[2]

Herein he probably refers to the eruption which had occurred a few years previously (b.c. 476).

Thucydides (b.c. 471-402) alludes in the last lines of the Third Book to several early eruptions of the mountain in the following terms: "In the first days of this spring, the stream of fire issued from Etna, as on former occasions, and destroyed some land of the Catanians, who live upon Mount Etna, which is the largest mountain in Sicily. Fifty years, it is said, had elapsed since the last eruption, there having been three in all since the Hellenes have inhabited Sicily."[3]

Virgil's oft-quoted description of the mountain (Eneid, Bk. 3) we give in the spirited translation of Conington:

"But Etna with her voice of fear
In weltering chaos thunders near.
Now pitchy clouds she belches forth
Of cinders red, and vapour swarth;
And from her caverns lifts on high
Live balls of flame that lick the sky:
Now with more dire convulsion flings
Disploded rocks, her heart's rent strings,
And lava torrents hurls to-day
A burning gulf of fiery spray."

Many other early writers speak of the mountain, among them Theokritos, Aristotle, Ovid, Livy, Seneca, Lucretius, Pliny, Lucan, Petronius, Cornelius Severus, Dion Cassius, Strabo, Diodorus Siculus, and Lucilius Junior. Seneca makes various allusions to Etna, and mentions the fact that lightning sometimes proceeded from its smoke.

Strabo has given a very fair description of the mountain. He asserts that in his time the upper part of it was bare, and covered with ashes, and in winter with snow, while the lower slopes were clothed with forests. The summit was a plain about twenty stadia in circumference, surrounded by a ridge, within which there was a small hillock, the smoke from which ascended to a considerable height. He further mentions a second crater. Etna was commonly ascended in Strabo's time from the south-west.

While the poets on the one hand had invested the mountain with various supernatural attributes, and had made it the prison-house of a chained giant, and the workshop of a swart god, Lucretius endeavoured to show that the eruptions and other phenomena could be easily explained by the ordinary operations of nature. "And now at last," he writes, "I will explain in what ways yon flame, roused to fury in a moment, blazes forth from the huge furnaces of Aetna. And, first, the nature of the whole mountain is hollow underneath, underpropped throughout with caverns of basalt rocks. Furthermore, in all caves are wind and air, for wind is produced when the air has been stirred and put in motion. When this air has been thoroughly heated, and, raging about, has imparted its heat to all the rocks around, wherever it comes in contact with them, and to the earth, and has struck out from them fire burning with swift flames, it rises up and then forces itself out on high, straight through the gorges; and so carries its heat far, and scatters far its ashes, and rolls on smoke of a thick pitchy blackness, and flings out at the same time stones of prodigious weight—leaving no doubt that this is the stormy force of air. Again, the sea, to a great extent, breaks its waves and sucks back its surf at the roots of that mountain. Caverns reach from this sea as far as the deep gorges of the mountain below. Through these you must admit [that air mixed up with water passes; and] the nature of the case compels [this air to enter in from that] open sea, and pass right within, and then go out in blasts, and so lift up flame, and throw out stones, and raise clouds of sand; for on the summit are craters, as they name them in their own language, what we call gorges and mouths."[4]

These ideas were developed by Lucilius Junior in a poem consisting of 644 hexameters entitled Aetna. The authorship of this poem has long been a disputed point; it has been attributed to Virgil, Claudian, Quintilius Varus, Manilius, and, by Joseph Scaliger[5] and others, to Cornelius Severus. Wensdorff was the first to adduce reasons for attributing the poem to Lucilius Junior, and his views are generally adopted. Lucilius Junior was Procurator of Sicily under Nero, and, while resident in the Island, he ascended Etna; and it is said that he proposed writing a detailed history of the mountain. He adopted the scientific opinions of Epicurus, as established in Rome by Lucretius, and was more immediately a disciple of Seneca. The latter dedicated to him his Quæstiones Naturales, in which he alludes more than once to Etna. M. Chenu speaks of the poem of Lucilius Junior as "sans doute très-póetique, mais assez souvent dur, heurté, concis, et parcela même, d'une obscurité parfois désespérante."[6] At the commencement of the poem, Lucilius ridicules the ideas of the poets as regards the connection of Etna with Vulcan and the Cyclops. He has no belief in the practice, which apparently prevailed in his time, of ascending to the edge of the crater and there offering incense to the tutelary gods of the mountain. He adopts to a great extent the tone and style of Lucretius, in his explanation of the phenomena of the mountain. Water filters through the
