Plowing and Sowing
Quite conveniently for Jason, Medea was a famous sorceress, magic potions being her stock in trade. She slipped Jason a salve which, when smeared on his body, made him proof against fire and brazen hooves. And so it was that Jason boldly approached the bulls and brooked no bullish insolence. Disregarding the flames that played merrily about his shoulders and steering clear of the hooves, he forced the creatures into harness and set about plowing the field. Nor was the subsequent sowing any great chore for the now-heartened hero. Gaily strewing seed about like a nymph flinging flowers in springtime, he did not stop to note the unusual nature of the seed.
