Well, Bulgarian is a Slavic language that uses cyrilic, and thus has some things in common with Russian, which I used to be able to communicate with somewhat proficiently. But that was a while back, so my attempt at translation will probably be laughable:
*Dagon - national god of philistines. Idol with the body of a fish and a head and hand on... Godliness(?) from the Asyrian-Bablyonian pantheon - white from ...?
**Silkag (originally Zilkag) - truthfully stands with his head in the clouds? - white from...?
As I said, pretty laughable, but maybe you can make more sense out of this. No bulgarian translation engines out there, huh?
