Jonson was also an important innovator in the specialised literary subgenre of the masque, which went through an intense development in the Jacobean era. His name is linked with that of Inigo Jones as co-developers of the literary and visual/technical aspects of this hybrid art. (For Jonson's masques, see: "The Masque of Blackness", "The Masque of Queens", etc.) The high costs of these spectacles, however, positioned the Stuarts far from the relative frugality of Elizabeth's reign, and alienated the middle classes and the Puritans with a prospect of waste and self-indulgent excess.
