You remember, do you not, how the sons of Pelops had driven the Heraclidae, or sons of Hercules, out of the peninsula which was called the Peloponnesus? This same peninsula is now called Morea, or the mulberry leaf, because it is shaped something like such a leaf, as you will see by looking at your map.

The Heraclidae had not gone away willingly, but were staying in Thessaly, in the northern part of Greece, where they promised to remain one hundred years without making any attempt to come back.

Shortly after the end of the Trojan War, this truce of a hundred years came to an end; and the Heraclidae called upon their neighbors the Dorians to join them, and help them win back their former lands.
