Alphonse Marie Louis de Prat de Lamartine was a French writer, poet and politician who was instrumental in the foundation of the Second Republic. Lamartine is famous for his partly autobiographical poem, "Le lac" (The Lake), which describes in retrospect the fervent love shared by a couple from the point of view of the bereaved man. Lamartine was masterly in his use of French poetic forms. Raised a devout Catholic, Lamartine became a pantheist, writing Jocelyn and La Chute d'un ange. He wrote Histoire des Girondins in 1847 in praise of the Girondists.
