Weekly letters from Seneca the Younger, translated and reproduced on parchment in the style of a 15th-century illuminated manuscript. A slow, meditative way to explore stoic philosophy.

Letterjoy's Stoic Letters subscription delivers one letter from Seneca's Epistulae Morales ad Lucilium each week, reproduced on parchment or vellum and beautifully typeset in the style of a 15th-century illuminated manuscript. The cadence is intentional: philosophy is meant to be savored, not binged. Each letter arrives with a decorated initial and ornamental design elements, making it as beautiful to look at as it is to read. Monthly or annual plans available.
