Cybele: The goddess Kybele in Greek, is derived from "from Kybelon". Kybelon is a mountain in Phrygia, from where Kybele hailed (Lidell-Scott)
Caesar: this was originally a proper name (
Julius Caesar) which eventually became synonymous to Emperor and it gave birth to expressions such as
Kaiser and Czar.
Julius Caesar was delivered by cutting through the walls of his mom's abdomen. The Caesarian section was named thus, not the other way around! According to
www.perseus.org,
Caesar is derived from caesius/caeruleus meaning "color of skin".
