Is there an attested use of the Greek word "petros" (meaning 'stone') as a given name, before it was given to Peter the Apostle?
Note: The name Jesus gave to Peter was most likely 'Kepha,' since that is what John 1:42 says, and since Jesus is most likely to have spoken Aramaic and not Greek. Also, Paul, author of probably the earliest books of the Bible, who had certainly met Peter in real life, called him both Cephas and Peter. So Peter was a name given to Simon/Kepha by those who knew him and spoke Greek. Just wanted to cut the pedants off at the pass.
