I think I can give a better Thracian connection to the origins of Zeus (a Hyperborean god), and Leto of Lycia, parents of Apollo, and the Delos sanctuary of Apollo. In Trace there is a location for the ancient people under the names Satrae. Bessi, and Dii. Their god was called Sabazios (Zeus). Their temple was at a site called Perperikon, and ties to Phrygians, too. The Satrae were the swordsman fighting stronghold and the name represents warrior fighting unit, and the blacksmiths, leaving two tribe names as Bessi, and Dii. I would claim a Hyperborean, Buri, or Burjan component. This deity is represented as riding a horse, and the horse treads on a serpent below. This would be the early Zeus, as a Hyperborean in Thrace regions. Relates to Dionysus. An early American (USA) flag exhibits a coiled snake, and reads: "Don't Tread On Me". Used in war efforts as a military flag of sorts.
