I've been sent the following photo of an inscription in a Unitarian church.
As best I can tell, it says:
Templum hoc [re]novat[u]m
est […]eribus denuo et inte[g]re[?]
regnante serenissimo dono do[…]o
principe Georgio Rakoci
Anno do[min]i 1640
In other words, this church was renovated once by ??? and again by a gift from the most serene reigning prince, George Rákóczi.
However, I'm curious what the other damaged parts might mean. What was the cause of the first renovation? And what is the word starting with D on the third line?
