In this article, I argue that existing literature discounts the role of self-improvement in Astellian friendship. To make this element central, I show how an Epicurean analysis of Astellian friendship brings self-improvement clearly into focus. On the way to centering self-improvement, I show how extant accounts imply self-improvement without explicitly setting up the architecture to explain this element of Astellian friendship. Self-improvement is centralized by way of three shared themes between the Epicurean Garden and the Astellian religious retirement: the motivation (...) to enter, the project inside, and the manner of friendship.
