Strabo Geographica 9.1.6
Furthermore, since the Peloponnesians and Ionians were having frequent disputes about their boundaries, on which, among other places, Crommyonia was situated, they made an agreement and erected a pillar in the place agreed upon, near the Isthmus itself, with an inscription on the side facing the Peloponnesus reading:
“This is Peloponnesus, not Ionia,” and on the side facing Megara, “This is not Peloponnesus, but Ionia.”
And though the writers of the histories of The Land of Atthis are at variance on many things, they all agree on this (at least all writers who are worth mentioning), that Pandion had four sons, Aegeus, Lycus, Pallas, and the fourth, Nisus, and that 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.”
These, then, are the proofs which writers use to show that Megaris was a part of Attica (original Greek).

Pausanias Description of Greece 1.5.3
I saw also among the eponymoi statues of Cecrops and Pandion, but I do not know who of those names are thus honored. For there was an earlier ruler Cecrops who took to wife the daughter of Actaeus, and a later—he it was who migrated to Euboea—son of Erechtheus, son of Pandion, son of Erichthonius. And there was a king Pandion who was son of Erichthonius, and another who was son of Cecrops the second. This man was deposed from his kingdom by the Metionidae, and when he fled to Megara—for he had to wife the daughter of Pylas king of Megara—his children were banished with him. And Pandion is said to have fallen ill there and died, and on the coast of the Megarid is his tomb, on the rock called the rock of Athena the Gannet (original Greek).
Pausanias Description of Greece 4.2.6
Lycus the son of Pandion also came to Arene, when he too was driven from Athens by his brother Aegeus, and revealed the rites of the Great Goddesses to Aphareus and his children and to his wife Arene; but it was to Andania that he brought the rites and revealed them there, as it was there that Caucon initiated Messene (original Greek).

Joy to you as well, Aegeus, son of wise Pandion! Where have you come from to be visiting the soil of this land?
Aegeus
I have come from the ancient oracle of Phoebus (original Greek).
Herodotus Histories 1.173
Such are their ways. The Lycians were from Crete in ancient times (for in the past none that lived on Crete were Greek). Now there was a dispute in Crete about the royal power between Sarpedon and Minos, sons of Europa; Minos prevailed in this dispute and drove out Sarpedon and his partisans; who, after being driven out, came to the Milyan land in Asia. What is now possessed by the Lycians was in the past Milyan, and the Milyans were then called Solymi. For a while Sarpedon ruled them, and the people were called Termilae, which was the name that they had brought with them and that is still given to the Lycians by their neighbors; but after Lycus son of Pandion came from Athens—banished as well by his brother, Aegeus—to join Sarpedon in the land of the Termilae, they came in time to be called Lycians after Lycus. Their customs are partly Cretan and partly Carian. But they have one which is their own and shared by no other men: they take their names not from their fathers but from their mothers, and when one is asked by his neighbor who he is, he will say that he is the son of such a mother, and rehearse the mothers of his mother. Indeed, if a female citizen marries a slave, her children are considered pure-blooded; but if a male citizen, even the most prominent of them, takes an alien wife or concubine, the children are dishonored (original Greek).
