Unheeded

My letter went unheeded.

"Then wars shall cease and savage times grow mild, / and Remus and Quirinus, brethren twain, / with hoary Faith and Vesta undefiled, / shall give the law. With iron bolt and chain / firm-closed the gates of Janus shall remain. / Within, the Fiend of Discord, high reclined / on horrid arms, unheeded in the fane, / bound with a hundred brazen knots behind, / and grim with gory jaws, his grisly teeth shall grind."

As one who, in a tangled brake apart, / on some lithe snake, unheeded in the briar, / hath trodden heavily, and with backward start / flies, trembling at the head uplift in ire / and blue neck, swoln in many a glittering spire. / So slinks Androgeus, shuddering with dismay.

My hearing, my child, has been sharpened by my blindness, and I can now draw conclusions from the slightest sounds, which formerly reached my ears as unheeded as they now approach yours.
