BRYKHON (or Brychon) was a River-God of Khalkidike in Thrake (now a region of northern Greece).
The Brykhon stream flowed into the Aegean between the peninsulars of Sithonia and Pallene in Thrakian Khalkidike. The two major neighbouring rivers were the Strymon to the east and Axios in the west.
Lycophron, Alexandra 1405 ff (trans. Mair) (Greek poet C3rd B.C.) :
"The plains of the Sithonians and the fields of Pallene, where the ox-horned [river] Brykhon, who served the Gigantes, fattens with his waters."
