Riccardo Petroni

[1] A distinguished jurist, he collaborated on the Sextus Liber Decretalium, which was promulgated in 1299 by Pope Boniface VIII.

The “Sextus Liber” was intended as a follow-up to the better remembered Decretals (in five books) of Gregory IX.

Pope Boniface VIII created Petroni a cardinal at the consistory of 1298 when the latter became Cardinal-Deacon of the church of Sant'Eustachio in Rome.

After he died in February of 1314, his mortal remains were transferred three years later to Siena, where Tino di Camaino was commissioned to build a monumental tomb for him, initially set up in the north transept of Santa Maria Assunta (but moved several times).

Riccardo Petroni was responsible for various buildings and monuments in his home city of Siena along with a Carthusian monastery.
