What kind of literary work are Horace’s Epistles?

Horace’s Epistles are literary letters written in verse, addressed to specific individuals or groups. As a literary form, an epistle is a composition in prose or poetry structured as a letter.12

Horace’s collection is characterized by a loose, conversational style and is more reflective and didactic than his earlier works, such as the Satires. While the first book of the Epistles revisits themes found in the Satires, the subsequent books focus primarily on literary topics and philosophical reflection. The third book, often referred to as the Ars poetica, serves as a notable example of this form, offering insights into the craft of poetry and the importance of decorum within literary genres.32

The Horatian tradition of the verse epistle, which addresses moral and philosophical subjects, has remained a popular and influential form in literature since the Renaissance.1
