Passage 8.37.8
παρὰ δὲ τὸν ναὸν τῆς Δεσποίνης ὀλίγον ἐπαναβάντι ἐν δεξιᾷ Μέγαρόν ἐστι καλούμενον, καὶ τελετήν τε δρῶσιν ἐνταῦθα καὶ τῇ Δεσποίνῃ θύουσιν ἱερεῖα οἱ Ἀρκάδες πολλά τε καὶ ἄφθονα. θύει μὲν δὴ αὐτῶν ἕκαστος ὅ τι κέκτηται· τῶν ἱερείων δὲ οὐ τὰς φάρυγγας ἀποτέμνει ὥσπερ ἐπὶ ταῖς ἄλλαις θυσίαις, κῶλον δὲ ὅ τι ἂν τύχῃ, τοῦτο ἕκαστος ἀπέκοψε τοῦ θύματος.
Near the temple of Despoina, after ascending a little, there is, on the right, a building called the Megaron. Here the Arcadians perform their rites and sacrifice to Despoina many rich offerings. Each devotee sacrifices whatever he possesses; however, they do not cut the throats of the victims as in other sacrifices, but instead each severs from the animal whatever limb the chance may bring.
