Passage 8.41.10
ἔστι δὲ ὕδατος ἐν τῷ ὄρει τῷ Κωτιλίῳ πηγή, καὶ ὅπου συνέγραψεν ἤδη τις ἀπὸ ταύτης τῷ ποταμῷ τὸ ῥεῦμα τῷ Λύμακι ἄρχεσθαι, συνέγραψεν οὔτε αὐτὸς θεασάμενος οὔτε ἀνδρὸς ἀκοὴν ἰδόντος· ἃ καὶ ἀμφότερα παρῆσαν ἐμοί· τὸ μὲν ποταμοῦ ῥεῦμα ὂν ἑωρῶμεν, τῆς δὲ ἐν τῷ Κωτιλίῳ πηγῆς οὐκ ἐπὶ πολὺ ἐξικνούμενον τὸ ὕδωρ ἀλλὰ ἐντὸς ὀλίγου παντάπασιν ἀφανὲς γινόμενον. οὐ μὴν οὐδὲ ὅπου τῆς Ἀρκάδων ἐστὶν ἡ πηγὴ τῷ Λύμακι, ἐπῆλθε πολυπραγμονῆσαί μοι. ἔστι δὲ ὑπὲρ τὸ ἱερὸν τοῦ Ἀπόλλωνος τοῦ Ἐπικουρίου χωρίον Κώτιλον μὲν ἐπίκλησιν, Ἀφροδίτη δέ ἐστιν ἐν Κωτίλῳ· καὶ αὐτῇ τε ναός τε ἦν οὐκ ἔχων ἔτι ὄροφον καὶ ἄγαλμα ἐπεποίητο.
There is on Mount Kotilion a spring of water, and whoever has maintained that the stream of the river Lymakos begins from this spring, has written neither from his own eyewitness account nor hearing from someone who had actually seen it. Both these conditions were present for me: for we saw in fact the stream flowing as a river, whereas the water from the spring on Mount Kotilion does not extend very far at all, but disappears altogether shortly after emerging. Moreover, I did not investigate precisely the spring that the Arcadians ascribe to the Lymakos. Above the sanctuary of Apollo Epikourios is a place named Kotilon, and in Kotilon there is a sanctuary of Aphrodite; her temple still stood, though it no longer had its roof, and a statue of her had been fashioned there.
