Upon a coin struck by Cæsar's heir, the almost equally famous Augustus (Consul B.C. 43, Emperor B.C. 29—A.C. 14), about twenty years before our era, we see a head of the Sun-God Bacchus upon one side; and on the reverse a man presenting a military standard, the banner of which is ornamented with a St. Andrew's cross.
Two other coins of the same reign and about the same date, have upon them representations of military standards bearing the same symbol.
Upon another coin struck by Augustus we see a crescent with a star or radiate sun within its horns, the ancient phallic symbol adopted by the followers of the prophet Muhammad centuries later.
A similar symbol occurs upon the coins of Hadrian (A.C. 117—138).
Upon two coins of Antoninus Pius (A.C. 138—161) we see the Sun-God Hercules plucking the Golden Apple from a tree around which the traditional serpent is coiled.
On another coin of the same reign the Sun-God Hercules can be seen holding a round object which admittedly represents the Golden Apple; that symbol both of the Sun-God as (1) the bi-sexual Giver of Life and (2) the personification of the Male Principle, and of the Goddess who represented (1) the Love of the two sexes and (2) the Female Principle.
Upon another coin Jove holds a similar looking object.
Many coins issued in the name of Annia Galeria Faustina the wife of Antoninus Pius, and by Marcus Aurelius (A.C. 161—180), and in the name of his wife Annia Faustina, have upon them representations of Venus the Goddess of Love holding a round object which is admittedly meant for the Golden Apple. The favourite legends are Venus Victrix, Venus Felix, and Venus Genetrix, and of phallic import; and in one instance the Goddess of Love holds an infant wrapped in swaddling clothes as well as the phallic apple.
Other coins of Marcus Aurelius or his wife have upon them representations of Eternity as a female figure holding a round object. In some cases the round object is surmounted by a Phœnix.
Upon a coin struck by Lucius Aurelius Verus (A.C. 160—169) that ruler is to be seen holding a round object surmounted by a Victory.
