But let neatness
please you...

Let your tongue, too, not be clammy;
your teeth free from yellowness; and let not
your foot wallop about, losing itself in the shoe
down at heel. Let not the cutting shockingly disfigure
your hair bolt upright; let your locks, let your
beard be trimmed by a skillful hand. Let your nails, too,
not be jagged, and let them be without dirt; and
let no hairs project from the cavities of your nostrils.
And let not the breath of your ill-smelling
mouth be offensive; and let not the
husband and the father of the flock
offend the nostrils. 

OVID ARS AMATORIA
