Passage 7.26.12
τῆς δὲ Αἰγειρατῶν ἔχονται Πελληνεῖς· πρὸς Σικυῶνος δὲ οὗτοι καὶ μοίρας τῆς Ἀργολίδος Ἀχαιῶν οἰκοῦσιν ἔσχατοι. τὸ δὲ ὄνομα ἐγένετο τῇ πόλει λόγῳ μὲν τῷ Πελληνέων ἀπὸ Πάλλαντος, τῶν Τιτάνων δὲ καὶ Πάλλαντα εἶναι λέγουσι, δόξῃ δὲ τῇ Ἀργείων ἀπὸ ἀνδρὸς Ἀργείου Πέλληνος· Φόρβαντος δὲ εἶναι τοῦ Τριόπα παῖδα αὐτὸν λέγουσιν.
Next to the territory of the people of Aigeira lies that of the Pelleneans. These inhabit the frontier of Achaia toward Sikyon and a part of Argolis. According to the Pellenean account, the name of their city is derived from Pallas, who is said to have been one of the Titans; on the other hand, according to the Argive tradition, the city received its name from an Argive named Pellen, who is said to have been the son of Phorbas and grandson of Triopas.
