Passage 3.12.10
ἑτέρα δὲ ἐκ τῆς ἀγορᾶς ἐστιν ἔξοδος, καθʼ ἣν πεποίηταί σφισιν ἡ καλουμένη Σκιάς, ἔνθα καὶ νῦν ἔτι ἐκκλησιάζουσι. ταύτην τὴν Σκιάδα Θεοδώρου τοῦ Σαμίου φασὶν εἶναι ποίημα, ὃς πρῶτος διαχέαι σίδηρον εὗρε καὶ ἀγάλματα ἀπʼ αὐτοῦ πλάσαι. ἐνταῦθα ἐκρέμασαν οἱ Λακεδαιμόνιοι τὴν Τιμοθέου τοῦ Μιλησίου κιθάραν, καταγνόντες ὅτι χορδαῖς ἑπτὰ ταῖς ἀρχαίαις ἐφεῦρεν ἐν τῇ κιθαρῳδίᾳ τέσσαρας χορδάς.
There is another exit from the marketplace, along which stands the building known as the Skias ("Place of Shelter"), where even now the people hold their assemblies. They say this Skias was built by Theodorus of Samos, who first discovered the method of casting iron and of shaping images out of it. Here the Lacedaemonians hung up the lyre of Timotheus of Miletus, having condemned him because he had introduced into musical performance four additional strings beyond the original seven.
