Baptisteria Sacra: An Iconographic Index of Baptismal Fonts (BSI) is an independent, not-for-profit, research project affiliated with the Centre for Reformation and Renaissance Studies at the University of Toronto. 

It is an international iconographic index of baptismal fonts from the early Christian period to the 17th century made available via the World Wide Web for scholarly research in a searchable electronic format which contains both images and text.   The individual record for each work aims to include a complete description of the font and its imagery.

The project evolved from a collection of medieval baptismal fonts from the Swedish island of Gotland, which was part of the preliminary research for Harriet M. Sonne's doctoral dissertation at the Institute of Art History at the University of Copenhagen in Denmark. Restricted originally to fonts which depicted scenes from the Childhood of Christ, it has since grown and expanded into a separate project, founded, developed and expanded by Harriet M. Sonne and Miguel A. Torrens.
