The project uBIQUity, which incorporates the "BI" of the Bible(s) and the "QU" of the Qur'ān in its title, is part of the larger PNRR project ITSERR - Italian Strengthening of the ESFRI RI RESILIENCE funded by the European Union - NextGenerationEU (CUP: B53C22001770006), and aims at investigating the sacred texts of Christianity and Islam and their reception in different environments and historical periods through two huge corpora: Greek and Latin Christian commentaries on the Bible(s) written from the Patristic age until the Late Byzantine period, and classical commentaries on the Qur'ān written in Arabic (tafāsīr) from the rise of Islam until the 15th century. By interweaving the research methods of the Humanities and Computer Science, uBIQUity aims to develop a new research tool that can identify with a higher degree of accuracy quotations/allusions to the Bible(s) and the Qur'ān in Christian and Islamic writings. Intertextual references, conscious or unconscious, work as invisible "places of memory", thus making the sacred texts "ubiquitous".
