The Iliad by Homer - (translated by: Pope)

The largest mantle her rich wardrobes hold, Most prized for art, and labour'd o'er with gold, Before the goddess' honour'd knees be spread, And twelve young heifers to her altars led: If so the power, atoned by fervent prayer, Our wives, our infants, and our city spare, And far avert Tydides' wasteful ire, That mows whole troops, and makes all Troy retire; Not thus Achilles taught our hosts to dread, Sprung though he was from more than mortal bed; Not thus resistless ruled the stream of fight, In rage unbounded, and unmatch'd in might.†
Book 6

So may the power, atoned by fervent prayer, Our wives, our infants, and our city spare; And far avert Tydides' wasteful ire, Who mows whole troops, and makes all Troy retire.†
Book 6 *

Thus from the tents the fervent legion swarms, So loud their clamours, and so keen their arms: Their rising rage Patroclus' breath inspires, Who thus inflames them with heroic fires: "O warriors, partners of Achilles' praise!†
Book 16
