A highly prized Human ability in both Ancient Greek and Rome was ''Virtue''. This was personified by a Deity called ''Virtus''. Male strength, courage, and character – were all attributed to this God. Especially popular as a ''Palace Deity'' of Roman Emperors – Virtus was portrayed in Art as a ''Young and Virile Man''. All ''Male Power'' flowed from Virtus to His Followers (if deemed worthy). This was determined in youth by a series of ''initiation rites'' common among Greek and later Roman boys at the age of 15 years.
