There does not seem any clear proof that the surnames which the Hellenistic kings in Asia and Egypt bore were necessarily connected with the cult, even if they were used to describe g.Surnames.
It is noteworthy that while modern books commonly speak of the surnames as assumed, the explanations given by our ancient authorities almost invariably suppose them to be given as marks of homage or gratitude (English Historical Review, xvi.
The official surnames must not, of course, be confused with the popular nicknames which were naturally not recognized by the court, e.g.
Her oldest priestesses, the dew-sisters - Aglauros, Herse, Pandrosos - signify the fertilization of the earth by the dew, and were probably at one time identified with Athena, as surnames of whom both Aglauros and Pandrosos are found.
Somewhat later the adoption of hereditary surnames and armorial bearings marked the existence of a large and noble class who either from the subdivision of fiefs or from the effects of the custom of primogeniture were very insufficiently provided for.
