How does the legend of Silvius Brabo explain the name Antwerp?

The legend of Silvius Brabo provides a popular, though folkloric, explanation for the name of Antwerp. According to the story, an evil giant named Druon Antigonus terrorized the Schelde River by demanding tolls from boatmen and severing the hands of those who refused to pay.12

The Roman soldier Silvius Brabo challenged the giant to a fight, defeated him, and cut off one of his hands. Brabo then flung the severed hand into the river. This act of "hand-throwing" is said to be the origin of the city's name, derived from the Dutch hand werpen (to throw a hand).2

While this tale is commemorated by the Brabo Fountain and reflected in the city's coat of arms, historians note that the name actually originates from the Germanic prefix anda ("against") and the verb werpen ("to throw"), likely referring to a structure built against the riverbank.2
