The Aeneid

As, when in tumults rise th' ignoble crowd, Mad are their motions, and their tongues are loud; And stones and brands in rattling volleys fly, And all the rustic arms that fury can supply: If then some grave and pious man appear, They hush their noise, and lend a list'ning ear; He soothes with sober words their angry mood, And quenches their innate desire of blood: So, when the Father of the Flood appears, And o'er the seas his sov'reign trident rears, Their fury falls: he skims the liquid plains, High on his chariot, and, with loosen'd reins, Majestic moves along, and awful peace maintains.†
