Ascapart

Ascapart (also spelled Ascupart, Ascapard, Ascopard, Ascopart and Asgapard) was a legendary giant from English folklore, supposedly conquered by Bevis of Hampton, though so huge as to carry Bevis, his wife, and horse under his arm.

He was 30 feet tall but the smallest of his land, and was defeated after his club (made from a whole tree) was swung at Sir Bevis and became stuck in soft ground.

In the Russian version of the tale, Bova Korolevich [ru], the character becomes Polkan, a centaur.

[2] Alongside the story of Bevis of Hampton, the giant appears in the local folklore of Hampshire and the New Forest; large medieval paintings of Sir Bevis and Ascupart can be found in the Southampton Bargate Monument Gallery (apparently 17th century restorations of early 14th century originals).

[3] David Foster Wallace coined the adjective ascapartic in his novel Infinite Jest, in reference to this giant.
