The dialogue between images and liminal spaces : the iconography of Maria Regina in eighth-century Rome

The iconography of Maria Regina in eighth-century Rome illustrates a deep connection between sacred painted images and architectural spaces in the basilicas of San Clemente, San Lorenzo fuori le Mura, and Santa Susanna. This essay focuses on the concept of zones of transition, i.e., liminal spaces, within sacred buildings. Distinct iconographic similarities among these sites suggest a common prototype drawn upon by artisans working at the same time. Altars situated in these transitional areas served both funerary and catechumenal purposes, emphasizing Mary's role as intercessor and guide. This consistent depiction underscores her significance in rites of passage, providing spiritual support during transitions such as physical death and the figurative death of baptism, thereby highlighting her importance in these ritual contexts.
