Epithets for Makedonian Kings

[keravnos]

I don't know any examples for a habit like that. Names that come to mind are things like "Savior", "The Great", "Fatherlover" , "Sieger", "Victor" and such.

ΦΙΛΟΠΑΤΩΡ, ΦΙΛΟΜΗΤΩΡ, ΦΙΛΑΔΕΛΦΟΣ aka "loved his father", "loved his mother" and "loved his brother" should be considered as

ΦΙΛΟΠΑΤΩΡ (spelled as Filopator)= "respected his father dearly and wants to continue his work" or "takes after his father whose work he aims to emulate" or "son who looked after his father, has his acceptance and continues his work".

Ancient Greeks were absolutely great in saying with one word what we modern ones can't say with 1000.

Anyways you Americans must know of a city celebrating that "brotherly love", Philadelphia.
