The church of San Callisto in Rome
This essay is based on an updated bibliographic and archive research, explores the history of the church
of San Callisto in Rome and addresses the following related issues. The reconstruction of the phases of
transformation of the architectural organism, elaborated by Roberta Maria Dal Mas and Angela Di Paola;
the critical reading of the interior space, created by Carmen Vincenza Manfredi; and the interpretation
of Giuseppe Momo’s project in relation to the pre-existing structures, carried out by Roberta Maria Dal
Mas. The study, supported by an unpublished relief, clarifies the unresolved questions concerning the
building, such as the controversial attribution of the plant to Orazio Torriani in the Roman context of the
late sixteenth and early seventeenth century and the role assumed by Momo in the reconfiguration of the
church, in relation to the previous restorations ordered by Pius IX and to the Roman architecture of the
first decades of the twentieth century.
