   “Knowe Lupus this, lest she thee call churle gratelesse, and vnkinde.”

   “Nor Guasco, nor Rudolfo left behinde, / Nor th'one nor th'other Guido, famous both, / Nor Eurard, nor Gernier must slip my mind, / To passe in gratelesse silence more then loth, / Whither do you louers and spouses kind?”

   “Corruption’s loathsome touch hath not yet marr’d / The beauty of Eve’s youngest, fresh as when / Beside yon priestless altar late he stood, / And, in the pious fervour of his soul), / Warm with the hope of an exalted faith, / And breathing forth the prayerful homage, paid / The votive off’ring grateful to his God. Sad lesson of mortality, and taught / At sadder cost—the fearful risk of heav’n. Ah, grateless unbeliever!”
