“It is easy to spread the sails to propitious winds, and to cultivate in different ways a rich soil, and to give lustre to gold and ivory, when the very raw material itself shines.”
Facile est ventis dare vela secundis,
Fecundumque solum varias agitare per artes,
Auroque atque ebori decus addere, cum rudis ipsa
Materies niteat.
Book III, line 26.
