Passage 2.10.2
ἐντεῦθέν ἐστιν ὁδὸς ἐς ἱερὸν Ἀσκληπιοῦ. παρελθοῦσι δὲ ἐς τὸν περίβολον ἐν ἀριστερᾷ διπλοῦν ἐστιν οἴκημα· κεῖται δὲ Ὕπνος ἐν τῷ προτέρῳ, καί οἱ πλὴν τῆς κεφαλῆς ἄλλο οὐδὲν ἔτι λείπεται. τὸ ἐνδοτέρω δὲ Ἀπόλλωνι ἀνεῖται Καρνείῳ, καὶ ἐς αὐτὸ οὐκ ἔστι πλὴν τοῖς ἱερεῦσιν ἔσοδος. κεῖται δὲ ἐν τῇ στοᾷ κήτους ὀστοῦν θαλασσίου μεγέθει μέγα καὶ μετʼ αὐτὸ ἄγαλμα Ὀνείρου καὶ Ὕπνος κατακοιμίζων λέοντα, Ἐπιδώτης δὲ ἐπίκλησιν. ἐς δὲ τὸ Ἀσκληπιεῖον ἐσιοῦσι καθʼ ἕτερον τῆς ἐσόδου τῇ μὲν Πανὸς καθήμενον ἄγαλμά ἐστι, τῇ δὲ Ἄρτεμις ἕστηκεν.
From here there is a path leading to the sanctuary of Asclepius. Upon entering the precinct, there stands on the left-hand side a two-chambered structure. In the first chamber lies a statue of Hypnos ("Sleep"), of which nothing remains except the head. The inner chamber is dedicated to Apollo Carneius, into which entrance is permitted exclusively to the priests. Within the stoa lies a very large bone from a sea monster, and beside it stands a statue representing Oneiros ("Dream"), as well as an image of Hypnos who is depicted putting a lion to sleep, called "Epidotes" ("the Giver"). Entering the sanctuary of Asclepius, there are two entrances; at one sits a statue of Pan, while at the other stands a statue of Artemis.
