The Consolation of Philosophy

The Consolation of Philosophy is a philosophical work by Boethius, written around the year 524. It has been described as the single most important and influential work in the West on Medieval and early Renaissance Christianity, and is also the last great Western work of the Classical Period.  
 
The Consolation of Philosophy was written during a one-year imprisonment Boethius served while awaiting trial – and eventual horrific execution – for the crime of treason under the Ostrogothic King Theodoric the Great. Boethius was at the very heights of power in Rome and was brought down by treachery. This experience inspired the text.  
 
It has been described as "by far the most interesting example of prison literature the world has ever seen."
