'Anastasius' originates from Greek, specifically the word 'Anastasios', where 'anastasis' meant 'resurrection'.

'Anastasius' changed from the Greek word 'Anastasios' and was adopted into Latin as 'Anastasius', eventually becoming the modern English name 'Anastasius'.

Initially, it meant 'resurrection' as a reference to the Christian concept, but over time it became used as a personal name, especially for saints and popes.
