De Otio (On Leisure) is a Latin work by Seneca (4 BC-65 AD). It survives in a fragmentary state. No degree of absolute certainty about the date of writing is possible, but it is thought by a majority of critics to have been written 62 AD or shortly after. Otio is from otium, this literally translates as leisure, vacant time, freedom from business.Seneca the Younger (c. 4 BC - AD 65), fully Lucius Annaeus Seneca and also known simply as Seneca (/ˈsɛnɪkə/), was a Roman Stoic philosopher, statesman, dramatist, and--in one work--humorist of the Silver Age of Latin literature. As a tragedian, he is best-known for his Medea and Thyestes.He was a tutor and later advisor to emperor Nero. He was forced to take his own life for alleged complicity in the Pisonian conspiracy to assassinate Nero. However, some sources state that he may have been innocent. His father was Seneca the Elder, his elder brother was Lucius Junius Gallio Annaeanus, and his nephew was the poet Lucan.
