"CLEANLINESS is next to Godliness" ... was Ovid's advice to young men setting out on amorous conquests in his poem Ars Amatoria.

August 17th is Men's Grooming Day and the ancient Romans apparently considered Antinous to be their role model because a BALSAMARIUM (bath unguent jar) in the form of the head of Antinous was hugely popular.
