“Iris! descend, and what we here ordain, Report to yon mad tyrant of the main. Bid him from fight to his own deeps repair, Or breathe from slaughter in the fields of air. If he refuse, then let him timely weigh Our elder birthright, and superior sway. How shall his rashness stand the dire alarms, If heaven’s omnipotence descend in arms? Strives he with me, by whom his power was given, And is there equal to the lord of heaven?”
