Matthew's Christ does not hand over the keys. He promises them: "I will give to thee the keys of the kingdom of heaven." Perugino paints the promise already executed. Two keys, gold and silver; the Vatican reads them as sovereignty, power conferred on Christ's first vicar on earth.
Behind, twice, Rome's Arch of Constantine: the emperor who legalised Christianity, his triumphal form set over the moment power changes hands. Popes are still elected in the Sistine Chapel.
And across the arches runs the patron's own name: Solomon's temple was richer, Sixtus IV's is holier.
