Holidays

Plato, Laws 2.653d (tr. T.J. Saunders):

The gods, however, took pity on the human race, born to suffer as it was, and gave it relief in the form of religious festivals to serve as periods of rest from its labours. They gave us the Muses, with Apollo their leader, and Dionysus; by having these gods to share their holidays, men were to be made whole again, and thanks to them, we find refreshment in the celebration of these festivals.

θεοὶ δὲ οἰκτίραντες τὸ τῶν ἀνθρώπων ἐπίπονον πεφυκὸς γένος, ἀναπαύλας τε αὐτοῖς τῶν πόνων ἐτάξαντο τὰς τῶν ἑορτῶν ἀμοιβὰς τοῖς θεοῖς, καὶ μούσας Ἀπόλλωνά τε μουσηγέτην καὶ Διόνυσον συνεορταστὰς ἔδοσαν, ἵν' ἐπανορθῶνται, τάς τε τροφὰς γενομένας ἐν ταῖς ἑορταῖς μετὰ θεῶν.
