The bolder of the people of Lemnos went to the foot of the mountain and discovered, to their amazement, that the rock opened like a door. They went inside, following the sound of the hammer. In the very depths of the mountain they saw a sight that had never been seen on earth before. There was a dark smithy in the heart of the burning mountain with a forge fire in which the power of the volcano burned, a great forge upon which Vulcan was shaping metal into things of dazzling beauty, and all about the smithy were the materials for making more; white steel, glowing copper, shining silver, and burnished brass and gold.

A strange company of apprentices, the Cyclopes, served Vulcan here. They had once been shepherds, but their peaceful occupation had been taken away from them because they had neglected to pay tribute to Apollo. Each had but a single eye, placed in the middle of the forehead, but they were using their great strength in the smithy of Vulcan to forge thunderbolts for Jupiter, to make a trident for Neptune and a quiver of arrows for Apollo. Beside Vulcan stood two wonderful hand-maidens of gold, who, like living creatures, moved about and helped the lame smith as he worked.

Vulcan, the despised of the gods, had chained fire and conquered the metals of the earth that he might make gifts for the gods and for the heroes.

Wonderful objects appeared at the doorway of Vulcan's shop and were carried to Mount Olympus. He shaped golden shoes, wearing which, the celestials were able to walk upon land or sea, and travel faster than thought flies. He made gold chairs and tables which could move without hands in and out of the halls of the gods. The celestial steeds were brought to Vulcan at Lemnos and he shod them so cleverly with brass that they were able to whirl the chariots of the gods through the air or on the waters with all the speed of the wind. He was even shaping brass columns for the houses of the gods. Vulcan had become the architect, smith, armorer, chariot-builder and the artist of all the work in Mount Olympus.

He was accomplishing more than this. Because he had captured fire and made the metals of the earth serve the ends of peace, the island of Lemnos became a safe, fertile land. Vineyards were planted and yielded rich harvests, flocks fed in green meadows, and Vulcan forged tools with which agriculture could be carried on. Ships from the other islands of Greece sailed to Lemnos and commerce, the strength of a nation, began.

In those days there was a great war being waged between the Trojans and the Greeks, and many hearts beat with hope at the prowess of a young Greek hero, Achilles. Hector, at the head of the Trojans, had stormed the Greek camp and set fire to many of their ships. A captain of the Greeks begged Achilles to lend him his armor that he might lead the soldiers against the forces of Troy.

"They may think me, in your mail, the brave Achilles," he said, "and pause from fighting, and the warlike sons of Greece, tired as they are, may breathe once more and gain a respite from the conflict."

So Achilles loaned this captain, Patroclus, his radiant armor and his chariot, and marshalled his men to follow into the field. At first the assault was successful, but there came a change of fortune. Patroclus' chariot driver was killed; then he met Hector in single combat, at the same time receiving a spear thrust at the back. So Patroclus fell, mortally wounded, and it was a great sorrow as well as a tragedy for Greece, for Patroclus had been Achilles' beloved friend, and Hector stole the armor of Achilles from his body. News of the defeat went even to Mount Olympus and Jupiter covered all the heavens with a black cloud.

But Thetis, the mother of Achilles, hastened to the smithy of Vulcan and told him that her son was in sore straits, having no suit of mail. She found the lame artisan of the gods at his forge, sweating and toiling, and with busy hands plying the bellows. But Vulcan laid by his work at once to weld a splendid suit of armor for Achilles. There was, first of all, a shield decorated with the insignia of war; then a helmet crested with gold and a corselet and greaves of metal so tempered that no dart could penetrate them. The task was done in a night and Thetis carried the armor to her son and laid it at his feet at dawn of the next day. No man before had ever worn such sumptuous armor.
