Cyranides

Λαβὼν οὖν ἀετίτην λίθον γλύψον ἀετόν, καὶ ὑπὸ τὸν λίθον ὑπόθες γίγαρτον σταφυλῆς, καὶ τὸ ἄκρον τοῦ πτεροῦ τοῦ ἀετοῦ εἶτε ἱέρακος, καὶ κατακλείσας φόρει· διαφυλάξει σε γὰρ ἀπὸ πάντων τῶν προειρημένων παθῶν. Ἔτι μὴν καὶ ἀξιόλογον καὶ προσφιλῇ συντυχίαις δυναστῶν, καὶ μεγάλων ἀνδρῶν καὶ περιεχόντων χάριν παρέξει· καὶ ἐπὶ ἑτέρων πολλῶν [ἄλλων] ὧν οὐ χρεία ἐστὶν λέγειν ποιήσει, καὶ οὕτως πέρας εἴληφεν τὸ πρῶτον στοιχεῖον ἄλφα.

So take an eagle-stone and engrave an eagle [on it], and under the stone put a grape-seed and the tip of a feather of the eagle, or of a hawk, and enclose [it] and wear it; for it will guard you from all the afflictions mentioned above. Moreover it will make [you] esteemed and well liked in meetings with rulers, and will win you the favour of great men and of those in power; and it will work in many other [further] matters which there is no need to tell. And so the first letter, Alpha, has come to its end.
