Passage 3.15.2
ἀπὸ δὲ τοῦ Δορκέως κρήνην τὴν πλησίον τοῦ ἡρῴου Δορκείαν, τὸ δὲ χωρίον τὸ Σέβριον καλοῦσιν ἀπὸ τοῦ Σεβροῦ. τοῦ Σεβρίου δέ ἐστιν ἐν δεξιᾷ μνῆμα Ἀλκμᾶνος, ᾧ ποιήσαντι ᾄσματα οὐδὲν ἐς ἡδονὴν αὐτῶν ἐλυμήνατο τῶν Λακώνων ἡ γλῶσσα, ἥκιστα παρεχομένη τὸ εὔφωνον.
From Dorceus comes the fountain nearby called Dorceia, close to his hero-shrine; and the place is called Sebrium after Sebrus. On the right-hand side of Sebrium is the tomb of Alcman, whose songs the Laconian tongue, least suited to harmonious expression, in no way impaired in their pleasantness.
