Ior Bock (Finnish: [i?or bok]; originally Bror Holger Svedlin; 17 January 1942 – 23 October 2010) was a Swedish-speaking Finnish tour guide, actor, mythologist and eccentric.
Ior Bock was a colourful media personality and became a very popular tour guide at the island fortress of Suomenlinna, where he worked from 1973 to 1998.
In 1984, Bock raised public interest and discussion when he claimed that his family line (Boxström) had been keepers of an ancient folklore tradition that provides insight into the pagan culture of Finland, including hitherto unknown autofellatio exercises connected to old fertility rites.
These stories are often known as the Bock saga.
His eccentric philosophical and mythological theories gained a small international following.
