The story
Derives from the ancient Greek myth where Jason sowed the teeth of a dragon into a field, from which they sprouted into an army of warriors. See also Ancient Greek ὀδόντες (του) δρᾰ́κοντος (odóntes (tou) drắkontos, “dragon's teeth”) and Σπαρτοί (Spartoí, “sown [men]”) from σπείρω (speírō, “to sow”).⁽ʷᵖ⁾
