**GRÉGOIRE, PIERRE (Tholosanus).** - Canonist, b. at Tolosa in 1540, d. at Pont-à-Mousson (Lorena) in 1597.

He was a renowned professor of law, described as « utriusque iuris et omnium scientiarum perita magnus », first at Cahors (1570-80), then at Tolosa (1580-82), and, from 1582, at Pont-à-Mousson, where he was also dean and chancellor. His principal work, Iuris canonici partitiones in V libros digestae (Lione 1594), constituted a noteworthy contribution to the systematic treatment of canon law. He also wrote, among other works: Paratitia iuris canonici (ivi 1595), a good compendium of the preceding work; Commentaria et adnotationes in Decretalium proemium (cf. Opera omnia, II, ivi 1612); Institutiones breves ac novae rei beneficiariae (ivi 1592); De usuris libri III (ivi 1592); Tractatus de appellationibus (posthumous, Urselles 1599). Among his works on civil law, the most notable is Syntagma iuris universi (Lione 1582), intended as a panoramic view of universal law.
