Satires, epistles, and art of poetry

In venturing to follow up my translation of the Odes of Horace by a version of the Satires and Epistles, I feel that I am in no way entitled to refer to the former as a justification of my boldness in undertaking the latter. Both classes of works are doubtless explicable as products of the same original genius: but they differ so widely in many of their characteristics, that success in rendering the one, though greater than any which I can hope to have attained, would afford no presumption that the translator would be found to have the least aptitude for the other.
