There are several legends behind this statue, but the most famous is the one about Duke Godfrey III of Leuven. In 1142, the troops of this two-year-old lord were battling against the troops of the Berthouts, the lords of Grimbergen, in Ransbeke (now Neder-over-Heembeek). The troops put the infant lord in a basket and hung it in a tree, to encourage them. From there, he urinated on the troops of the Berthouts, who eventually lost the battle.
