Iancu Constantin Vissarion (born Iancu Visarion, also credited as Ion Vissarion; 2 February 1879 – 5 November 1951) was a Romanian prose writer, poet, and political agitator, also known as an inventor, esotericist, and promoter of pseudoscience. He lived most of his life in Costeștii din Vale village, and was advertised as one of the rare and self-taught "peasant writers"; however, he held a variety of jobs, from notary to porter, and eventually to wealthy landowner. His literary beginnings were as a student of Romanian folklore and poet-raconteur, with an inclination toward agrarian socialism. Vissarion's anti-establishment positioning saw his participation in the peasants' revolt of early 1907, which resulted in his capture by the Land Forces and his narrowly escaping the death penalty.
