نامه‌های اخلاقی به لوکیلیوس

The Epistulae morales ad Lucilium (Latin for moral letters to Lucilius) is a collection of 124 letters which were written by Seneca the Younger at the end of his life, during his retirement, and written after he had worked for the Emperor Nero for fifteen years. They are addressed to Lucilius, the then procurator of Sicily, although he is known only through Seneca's writings. Whether or not Seneca and Lucilius actually corresponded, or whether in fact Seneca created the work as a form of fiction, is not clear from the historical record.
