Passage 2.28.2
ἐς δὲ τὸ ὄρος ἀνιοῦσι τὸ Κόρυφον, ἔστι καθʼ ὁδὸν Στρεπτῆς καλουμένης ἐλαίας φυτόν, αἰτίου τοῦ περιαγαγόντος τῇ χειρὶ Ἡρακλέους ἐς τοῦτο τὸ σχῆμα. εἰ δὲ καὶ Ἀσιναίοις τοῖς ἐν τῇ Ἀργολίδι ἔθηκεν ὅρον τοῦτον, οὐκ ἂν ἔγωγε εἰδείην, ἐπεὶ μηδὲ ἑτέρωθι ἀναστάτου γενομένης χώρας τὸ σαφὲς ἔτι οἷόν τε τῶν ὅρων ἐξευρεῖν. ἐπὶ δὲ τῇ ἄκρᾳ τοῦ ὄρους Κορυφαίας ἐστὶν ἱερὸν Ἀρτέμιδος, οὗ καὶ Τελέσιλλα ἐποιήσατο ἐν ᾄσματι μνήμην.
On the way up Mount Koryphum, there is an olive-tree called "Strepte" ("Twisted"), formed by Hercules who bent it with his hand into that particular shape. Whether he set this as a boundary for the people of Asine in Argolis as well, I myself cannot say; for even where the land has not been devastated, it is no longer possible to clearly identify the boundary markers. On the summit of Mount Koryphum there is a sanctuary of Artemis Koryphaia, to which Telesilla also refers in a poem.
