The boy grew to be very large and strong. While he was yet a youth he slew a lion of great size that had killed many of his father’s cattle. He went home wearing the lion’s skin as a sign of his victory.

Because he was so brave the King of Thebes gave his daughter to him in marriage and he lived happily with her for many years. But a sudden insanity came upon him during which he mistook his wife and children for wild beasts and shot them down with his bow and arrows. When Herakles recovered from his insanity and saw what he had done his grief was boundless.

CHAPTER II
HERAKLES IS DOOMED TO SERVE EURYSTHEUS

The wrath of Hera followed Herakles. When Zeus saw that Hera’s heart was filled with anger toward Herakles, he mused within his own mind how he might best appease her resentment and protect the young man.

So he called the gods together in council and they advised that Herakles be placed in bondage to his uncle Eurystheus, to serve him as a slave, and they ordained that he should perform twelve hard tasks, after which he would be numbered among the gods.

Eurystheus was a mean fellow, stupid and cowardly. He was glad enough to have a chance to bully a man wiser and stronger than himself. He was born in Tiryns, a great fortress with many castles, built upon a large rock, but he had been made King of Argos and lived in the capital, Mykenæ, and he resolved to keep Herakles as far away from the kingdom as possible, for in his heart he was afraid of him.

Herakles was grieved at being compelled to serve a man so much below him in strength and character, so he consulted the oracle at Delphi to see if there was any escape, but he did not murmur, for he was willing to obey the law of the gods.

The oracle of Delphi was a mysterious influence, a divine spirit which expressed itself through a priestess living in a sacred temple. It was supposed to be the voice of the god Apollo using this human agency for making known his will to men. The priestess became inspired to utter Apollo’s holy laws by sitting on a golden tripod (or stool with three legs) over a chasm in the rock, from whence arose a sacred, sulphurous vapor which she breathed in as the breath of the god, and which caused her to breathe out his commands in wonderful sayings.

The chasm from which the vapor issued was called The Chasm of the Oracle, and was in a large apartment or room in the temple. This celebrated temple had many columns of marble and splendid rooms made beautiful with thousands of marble statues. It stood on the side of Mount Parnassos, whose snow-covered head reaches into the clouds and looks down into the blue Gulf of Corinth below it to the south.
