Flavio Chigi (1631–1693)

Flavio Chigi (December 8, 1631 – September 13, 1693) was an Italian Roman Catholic cardinal and art collector. Born in Siena, he was the nephew of Pope Alexander VII (Fabio Chigi).

He was made a cardinal deacon in 1657 by his uncle and served as Cardinal Nephew. He received several titles during his career, including Cardinal Deacon of Santa Maria in Portico (1656-1661), Cardinal Deacon of San Giorgio in Velabro (1661-1663), Cardinal Deacon of Sant'Angelo in Pescheria (1663-1686), Cardinal Priest of Santa Maria del Popolo (1686-1689), and Cardinal Priest of San Crisogono (1689-1693).

Chigi played a significant role in the papal administration during Alexander VII's pontificate. He was involved in diplomatic missions, including negotiations with France. After his uncle's death in 1667, Chigi's influence diminished. He participated in several papal conclaves, including those of 1667, 1669-1670, 1676, 1689, and 1691.

He is also remembered as a notable patron of the arts. He amassed a significant art collection, which included paintings, sculptures, and antiquities. He supported artists and architects, contributing to the artistic landscape of Rome during his lifetime.
