Translation of "Oreste" in English

" Mais Oreste en fureur, qu'incessamment tourmente / le fouet de Némésis, le regret d'une amante, / jette aux pieds de l'autel son rival égorgé, / et ce rapt criminel par un crime est vengé. "

"But mad with love's despair, / and stung with Furies for his spouse denied, / at length Orestes caught the wretch unware, / e'en by his father's shrine, and smote him then and there."
