Horace: Book Ii. Ode 9

Clouds do not always veil the skies, Nor showers immerse the verdant plain; Nor do the billows always rise, Or storms afflict the ruffled main. Nor, Valgius, on the Armenian shores Do the chain'd waters always freeze; Not always furious Boreas roars, Or bends with violent force the trees. But you are ever drown'd in tears, For Mystes dead you ever mourn; No setting Sol can ease your cares, But find you sad at his return. The wise experienced Grecian sage Mourn'd not Antilochus so long; Nor did King Priam's hoary age So much lament his slaughter'd son. Leave off, at length, these woman's sighs, Augustus' number'd trophies sing, To whom all nations tribute bring. Niphates rolls an humbler wave, At length th' undaunted Scythian yields, Content to live the Roman slave, And scarce forsakes his native fields.
