Aegeus. In Greek mythology, Aegeus was an archaic figure in the founding myth of Athens. The goat-man who gave his name to the Aegean Sea was, next to Poseidon, the father of Theseus, the founder of Athenian institutions and one of the kings of Athens. Aegeus was the son of Pandion II, king of Athens and Pylia, daughter of King Pylas of Megara and thus, brother to Pallas, Nysus and Lykos. But, in some accounts, he was regarded as the son of Scyrius or Phemius and was not of the stock of the Erechtheids, since he was only an adopted son of Pandion. Aegeus' first wife was Meta, daughter of Hoples and his second wife was Chalciope, daughter of Rhexenor, neither of whom bore him any children. Aegeus was born in Megara where his father Pandion had settled after being expelled from Athens by the sons of Metion who seized the throne. After the death of Pandion, now king of Megara, Aegeus in conjunction with his three brothers successfully attacked Athens, took control over the government and expelled the usurpers, the Metionids. Then, they divide the power among themselves but Aegeus obtained the sovereignty of Attica, succeeding Pandion to the throne. It has been said that Megara was at the time a part of Attica, and that Nisus received his part when he became king of that city. Lycus became king of Euboea whereas Pallas received the southern part of the territory. Aegeus, being the eldest of the brothers, received what they all regarded as the best part: Athens. The division of the land was explained further in the following text by the geographer Strabo:. when Attica was divided into four parts, Nisus obtained Megaris as his portion and founded Nisaea. Now, according to Philochorus, his rule extended from the Isthmus to the Pythium, but according to Andron, only as far as Eleusis and the Thriasian Plain. Although different writers have stated the division into four parts in different ways, it suffices to take the following from Sophocles: Aegeus says that his father ordered him to depart to the shorelands, assigning to him as the eldest the best portion of this land; then to Lycus he assigns Euboea's garden that lies side by side therewith; and for Nisus he selects the neighboring land of Sceiron's shore; and the southerly part of the land fell to this rugged Pallas, breeder of giants. Later on, Lycus was driven from the territory by Aegeus himself, and had to seek refuge in Arene, Messenia. Pallas and his fifty sons revolted at a later time, being crushed by Aegeus' son Theseus. Still without a male heir with his previous marriages, Aegeus asked the oracle at Delphi for advice. According to Pausanias, Aegeus ascribed this misfortune to the anger of Aphrodite and in order to conciliate her introduced her worship as Aphrodite Urania in Athens. The cryptic words of the oracle were Do not loosen the bulging mouth of the wineskin until you have reached the height of Athens, lest you die of grief. Aegeus did not understand the prophecy and was disappointed. This puzzling oracle forced Aegeus to visit Pittheus, king of Troezen, who was famous for his wisdom and skill at expounding oracles. Pittheus understood the prophecy and introduced Aegeus to his daughter, Aethra, when Aegeus was drunk. They lay with each other, and then in some versions, Aethra waded to the island of Sphairia and bedded Poseidon. When Aethra became pregnant, Aegeus decided to return to Athens. Before leaving, he buried his sandal, shield, and sword under a huge rock and told her that, when their son grew up, he should move the rock and bring the weapons to his father, who would acknowledge him. Upon his return to Athens, Aegeus married Medea, who had fled from Corinth and the wrath of Jason. Aegeus and Medea had one son named Medus. When Theseus grew up, he found his father's belongings left for him and went to Athens to claim his birthright. Aegeus recornized him as a son by his sword. Medea, Aegeus' wife perceived Theseus to be a threat for her children's inheritance and first tried to discredit and then to poison Theseus. When Aegeus discovered these schemes, he drove Medea out of Athens. While visiting in Athens, King Minos' son, Androgeus managed to defeat Aegeus in every contest during the Panathenaic Games. Out of envy, Aegeus sent him to conquer the Marathonian Bull, which killed him. Minos was angry and declared war on Athens. He offered the Athenians peace, however, under the condition that Athens would send seven young men and seven young women every nine years to Crete to be fed to the Minotaur, a vicious monster. This continued until Theseus killed the Minotaur with the help of Ariadne, Minos' daughter. After his adventures in Crete, Theseus returned by ship to Athens.
