Ilus, being satisfied that the statue was the sign for which he had prayed, immediately set about building his city, and thus Troy was founded. It soon became the capital of Troas and the richest and most powerful city in that part of the world. During the reign of Laomedon, son of Ilus, its mighty walls were erected, which in the next reign withstood for ten years all the assaults of the Greeks. These walls were the work of no human hands. They were built by the ocean god Neptune. This god had conspired against Jupiter and attempted to dethrone him, and, as a punishment, his kingdom of the sea was taken away from him for one year, and he was ordered to spend that time in the service of the king of Troy.
In building the great walls, Neptune was assisted by Apollo, who had also been driven from Olympus for an offense against Jupiter. Apollo had a son named Æs-cu-laʹpi-us, who was so skilled a physician that he could, and did, raise people from death to life. Jupiter was very angry at this. He feared that men might forget him and worship Æsculapius. He therefore hurled a thunderbolt at the great physician and killed him. Enraged at the death of his son, Apollo threatened to destroy the Cyclops, the giant workmen of Vulcan, who had forged the terrible thunderbolt. Before he could carry out his threat, however, Jupiter expelled him from heaven. He remained on earth for several years, after which he was permitted to return to his place among the gods on the top of Mount Olympus.

Though Neptune was bound to serve Laomedon for one year, there was an agreement between them that the god should get a certain reward for building the walls. But when the work was finished the Trojan king refused to keep his part of the bargain. Apollo had assisted by his powers of music. He played such tunes that he charmed even the huge blocks of stone, so that they moved themselves into their proper places, after Neptune had wrenched them from the mountain sides and had hewn them into shape. Moreover, Apollo had taken care of Laomedon's numerous flocks on Mount Ida. During the siege, Neptune, in a conversation with Apollo before the walls of Troy, spoke of their labors in the service of the Trojan king:
"Hast thou forgot, how, at the monarch's prayer,
We shared the lengthen'd labors of a year?
Troy walls I raised (for such were Jove's commands),
And yon proud bulwarks grew beneath my hands:
Thy task it was to feed the bellowing droves
Along fair Ida's vales and pendant groves."
Pope, Iliad, Book XXI.
Long before this, however, the two gods had punished Laomedon very severely for breaking his promise. Apollo, after being restored to heaven, sent a plague upon the city of Troy, and Neptune sent up from the sea an enormous serpent which killed many of the people.
A great serpent from the deep,
Lifting his horrible head above their homes,
Devoured the children.
