Patron of the Arts

ἦσαν δὲ κύριοι μὲν τῶν πραγμάτων διὰ τὰ ἀξιώματα καὶ καὶ τὰς ἡλικίας Ἵππαρχος καὶ Ἱππίας, πρεσβύτερος δὲ ὢν ὁ Ἱππίας καὶ τῇ φύσει πολιτικὸς καὶ ἔμφρων ἐπεστάται τῆς ἀρχῆς. ὁ δὲ Ἵππαρχος παιδιώδης καὶ ἐρωτικὸς καὶ φιλόμουσος ἦν καὶ τοὺς περὶ Ἀνακρέοντα καὶ Σιμωνίδην καὶ τοὺς ἄλλους ποιητὰς οὗτος ἦν ὁ μεταπεμπόμενος...

This is from Aristotle's Athenian Constitution (18.1), in which he says that Hippias, as the older and more prudent (ἔμφρων) brother, was in charge of the government, while Hipparchos, the playful, amorous, and art loving one (παιδιώδης καὶ ἐρωτικὸς καὶ φιλόμουσος), sought out poets.
