Agostino Pallavicini, a member of the Genoese branch of the Pallavicini family and the future doge of Genoa, sits enveloped by the sumptuous, flowing red robes worn in his role as ambassador to the Pope. The wide expanse of fabric, spectacularly rendered, seems to have a life of its own and almost threatens to take over the painting. The luxurious swirl of cloth, its brilliant sheen, and the way it glimmers and reflects light display Anthony van Dyck's virtuosity as a painter. The family coat of arms seen on the drapery behind the sitter at the left, along with other documented portraits, firmly establishes Pallavicini's identity.
