does anyone know what "Ethro Zeo Natro Zeus" might mean?

Answer 1

I can't seem to find it online, but am going to take a wild guess
Natro I think means born from ethro might mean the prayer and zeo might mean beginning
so.......
The Prayer began with the birth of Zeus
or maybe something along those lines........

Answer 2

It means hail father Zeus....or something like that. Its the beginning of a prayer to him that's similar to the Christian Our Father
