The Wild Boy of Hesse
A wild boy found in the woods of Hesse, Germany, in 1341. He appeared to be about 7 years old and supposedly had been kept by wolves.
This boy apparently died soon after being captured, but a second wild boy was seized three years later (1344) in the same region and reportedly lived to the age of 80 years.
According to records, both children were wild and immune to cold and discomfort, besides not being able to stand upright, consequently having to move around on all fours.
