Poème sur le désastre de Lisbonne
The "Poème sur le désastre de Lisbonne" (English title: Poem on the Lisbon Disaster) is a poem in French composed by Voltaire as a response to the 1755 Lisbon earthquake. It is widely regarded as an introduction to Voltaire's 1759 acclaimed novel Candide and his view on the problem of evil. The 180-line poem was composed in December 1755 and published in 1756. It is considered one of the most savage literary attacks on optimism.
