Passage 8.37.10
ὑπὲρ δὲ τὸ καλούμενον Μέγαρόν ἐστιν ἄλσος τῆς Δεσποίνης ἱερὸν θριγκῷ λίθων περιεχόμενον, ἐντὸς δὲ αὐτοῦ δένδρα καὶ ἄλλα καὶ ἐλαία καὶ πρῖνος ἐκ ῥίζης μιᾶς πεφύκασι· τοῦτο οὐ γεωργοῦ σοφίας ἐστὶν ἔργον. ὑπὲρ δὲ τὸ ἄλσος καὶ Ἱππίου Ποσειδῶνος, ἅτε πατρὸς τῆς Δεσποίνης, καὶ θεῶν ἄλλων εἰσὶ βωμοί· τῷ τελευταίῳ δὲ ἐπίγραμμά ἐστι θεοῖς αὐτὸν τοῖς πᾶσιν εἶναι κοινόν.
Above the building called the Megaron there is a grove sacred to Despoina, enclosed by a stone wall; within it various trees are growing, including an olive and a holm-oak, sprung from a single root. This marvel is not due to any skill of a gardener. Above the grove there are altars to Poseidon Hippios—as father of Despoina—and to other gods; on the last of these altars there is an inscription stating that it is shared among all the gods.
