Strabo, Geography 14. 1. 23 (trans. Jones) (Greek geographer C1st B.C. to C1st A.D.) :
"The temple [of Artemis at Ephesos] . . . was the work of Kheirokrates (Cheirocrates), the same man who built Alexandreia and the same man who proposed to Alexandros (Alexander) [the Great] to fashion Mount Athos into his likeness, representing him as pouring a libation from a kind of ewer into a broad bowl, and to make two cities, one on the right of the mountain and the other on the left, and a river flowing from one to the other."
