cauchi’s only work which is still extant is institutionum decisiones d[ivi] iustiniani imperatoris ("teachings about the conclusions of the holy emperor justinian"), written in 1699. the manuscript is held at the national library of malta, valletta, and marked as ms. 1286#1. it contains fifty-four back to back folios, and is basically a philosophical commentary on roman law. the content was part of cauchi’s "corpus" of lectures given at messina, sicily, in or before the date of its composition. the manuscript is divided into ‘conclusions’ (each called a "decisio") and numbered paragraphs.
