Anthesteria is almost here

Alexander Polyhistor, Successions of Philosophers FGrHist 273 F 93
Hermes is the steward of souls, and for that reason is called Hermes the Escorter, Hermes the Keeper of the Gate, and Hermes of the Underworld, he brings upwards the purified souls, but impure souls were not allowed to approach each other, much less to come close to pure souls, since they were fettered in unbreakable bonds by the Erinyes. And all the air is full of souls and they are called daimones and heroes; and they carry to men dreams, portents, diseases, and purification, averting by expiatory sacrifices, all divination and omens are related to them.

τὸν δ’ Ἑρμῆν ταμίαν εἶναι τῶν ψυχῶν καὶ διὰ τοῦτο πομπαῖον λέγεσθαι καὶ πυλαῖον καὶ χθόνιον, ἐπειδήπερ οὗτος καὶ εἰσπέμπει ἀπὸ τῶν σωμάτων τὰς ψυχὰς ἀπό τε γῆς καὶ ἐκ θαλάττης· καὶ ἄγεσθαι μὲν τὰς καθαρὰς ἐπὶ τὸν ὕψιστον, τὰς δ’ ἀκαθάρτους μήτ’ ἐκείναις  πελάζειν μήτ’ ἀλλήλαις, δεῖσθαι δ’ ἐν ἀρρήκτοις δεσμοῖς ὑπ’εἶναί τε πάντα τὸν ἀέρα ψυχῶν ἔμπλεων· καὶ ταύτας δαίμονάς τε καὶ ἥρωας ὀνομάζεσθαι· καὶ ὑπὸ τούτων πέμπεσθαι ἀνθρώποις τούς τ’ ὀνείρους καὶ τὰ σημεῖα νόσους τε, καὶ οὐ μόνον ἀνθρώποις ἀλλὰ καὶ προβάτοις καὶ τοῖς ἄλλοις κτήνεσιν· εἴς τε τούτους γίνεσθαι τούς τε καθαρμοὺς καὶ ἀποτροπιασμοὺς μαντικήν τε πᾶσαν καὶ κληδόνας καὶ τὰ ὅμοια.
