Brewer's: Cupid's Golden Arrow
Virtuous love. “Cupid's leaden arrow,” sensual passion.
Deque sagittifera promsit duo tela pharetra Diversorum operum; fugat hoc, facit illud amorem. Quod facit auratum est, et cuspide fulget acuta-, Quod fugat obtusum est, et habet sub arundine plumbum.'
Ovid: Tale of Apollo and Daphnë.
I swear to thee by Cupid's strongest bow; By his best arrow with the golden head By that which knitteth souls and prospers love.
Shakespeare Midsummer Night's Dream.
