Hellenistic rulers: conceivable epithets

[machinor]

This thread is really becoming great.

Did the ancient hellenes have an Epithet for
"the lion"
"ruler of all hellenes" - in this case not just of thoose in hellas but of all Hellenes in the world.
"lord of all the seas and land under the sky" - I bit fantasy like but is there a similar term?

I would also have another question: could anyone tell me how expressions like "Europe of the Seleucids", "Europe of the nomads", "horsemen of the east", "horsemen of hades" might have sounded like in ancient Greek. (I quess my fantasy got a bit too loose)

IIRC, "Lion" would be "Leonidas" (ΛΕΟΝΙΔΑΣ). "Ruler of all Hellenes" would probably be "Hellenokrator" (ΈΛΛΗΝΟΚΡΑΤΩΡ).
