Epictetus 
A Selection from the Discourses of Epictetus, with the Encheiridion [EPUB ebook] 

According to Wikipedia: ‘Epictetus (Ancient Greek: Ἐπίκτητος; AD 55 – AD 135) was a Greek sage and Stoic philosopher. He was born a slave at Hierapolis, Phrygia (present day Pamukkale, Turkey), and lived in Rome until banishment when he went to Nicopolis in northwestern Greece where he lived the rest of his life. His teachings were noted down and published by his pupil Arrian in his Discourses.’
