This Element presents new cultural, social, and economic perspectives on the eighteenth-century London masquerade through an in-depth analysis of the classic domino costume. Constructing the object biography of the domino through material, visual, and written sources will bring together various experiences of the masquerade and expand the existing geographical, chronological, and socio-economic scope of the entertainment beyond the masquerade event itself. This Element will examine the domino's physical and figurative movements from the masquerade warehouse, through eighteenth-century fashionable society, and into print and visual culture. It will draw upon masquerade warehouse records, newspapers, manuscripts, prints, and physical objects to establish a comprehensive understanding of the domino and how it reflected contemporary experiences of the real and imagined masquerade. Analysing the domino through interdisciplinary methodologies illustrates the impact material and visual sources can have on reshaping existing scholarship.
