The humour of these nicknames is not striking. Jack the Bald (calvus) is Calvin; Jack with a lantern represents the enthusiast with his inward light. Cf. Hudibras, Part I, Cant, i, 1. 505
''Tis a dark lantern of the spirit,
Which none see by but those that bear it.'
Dutch Jack is the Anabaptists, represented by John of Leyden: French Hugh stands for the Huguenots: Tom the beggar for Les Gueux — the Ragamuffins — the name applied to the Flemish Huguenots: and Knocking Jack of the north for John Knox and the Scotch Presbyterians.
