Proper noun
Zonaras
A surname from Byzantine Greek — famously held by:
John Zonaras (fl. 12th C.), Byzantine Constantinopolitan chronicler and theologian
He sent his successful commander Aureolus against the rebels, however, and the decisive battle was fought in the spring or early summer of 261, most likely in Illyricum, although Zonaras locates it in Pannonia. Source: Internet
The "Zonaras proviso", the claim that Easter must always follow Nisan 14 in the Hebrew calendar, was not formulated until after some centuries. Source: Internet
