2. Yet the fowl of the desert, when danger encroaches, 10 Dares fearless to perish defending her brood, Though the fiercest of cloud-piercing tyrants approaches Thirsting-ay, thirsting for blood; And demands, like mankind, his brother for food; Yet more lenient, more gentle than they; 15 For hunger, not glory, the prey Must perish.
