The Roman philosopher Seneca the Younger commits suicide on orders from Emperor Nero. Although Seneca was almost certainly not part of the recent Pisonian conspiracy to kill Nero, Nero wanted him dead anyway.
An important Stoic philosopher, his Consolations (written while in exile) seek to explain the natural state of the universe in a detached manner.
Seneca's Consolations don't actually offer solace; instead, the reader is expected to learn to become less disturbed by the uncontrollable nature of the world around us. There is some criticism of Seneca, both contemporary and modern, regarding his apparent failure to actually live according to the Stoic principles he expounds in his philosophical works.
