SIRAR represents one of the main results of the four-year research project Lived Ancient Religion in North Africa (LARNA), led by Valentino Gasparini at the Universidad Carlos III de Madrid (2018-2022) and funded by the Talent Attraction Program of the Autonomous Community of Madrid (2017-T1/HUM-5709), in synergy with the Instituto de Historiografía Julio Caro Baroja (Madrid), the Scuola Archeologica Italiana di Cartagine (Tunis/Sassari) and the Université Jean Jaurès (Toulouse). LARNA aimed at exploring how different local small-scale religious providers and entrepreneurs filtered, appropriated, adapted, instrumentalised, or even invented new religious offers in Roman Africa. Given the very abundant first-hand information provided in North Africa by the epigraphic evidence, it was immediately clear that the LARNA project could not be successfully carried out without drawing (among the as many as 60,000 Neo-Punic, Greek and Latin available inscriptions) from the tituli which could allow to explore empirically the local, individual religious preferences. Thus, LARNA started an intense work of selection of the significant material, which was finally collected by José Carlos López-Gómez (now at the Universidad de Málaga) and the team of the UC3M’s Library of Humanities, Communication and Documentation within an open source web-publishing platform provided by Omeka S. The Sylloge Inscriptionum Religionis Africae Romanae (SIRAR) currently collects more than 5,700 geo-referenced inscriptions. This database not only represents a key-tool for all researchers studying religion in Roman Africa (and, in general, in the ancient Mediterranean), but dedicates a specific attention to ancient divine onomastics, thanks to a meticulous work of methodological conceptualization led in synergy with the team of the EPIDI project (Epítetos Divinos: experiencia religiosa y relaciones de poder en Hispania): see https://humanidadesdigitales.uc3m.es/s/DEPHis/page/inicio. In order to constantly update SIRAR and make it as perfectible as possible, visitors are kindly invited to contact us in case they detect mistakes, suggest new published readings of existing entries, or propose the inclusion of new inscriptions.
