Santa
The legend and character of Santa Claus derives directly from St Nicholas of Myra (near modern-day Demre in Antalya Province, Turkey).
Apparently he was a very generous fellow. Although he did once lose his shit and slap Arius in the face at the first ecumenical council in AD 325.
St Nicholas is venerated by the Orthodox church as the patron saint of children, barrel makers, sailors, merchants, the falsely accused, repentant thieves, brewers, pharmacists, archers, pawnbrokers and broadcasters.
