St. Jerome in the Wilderness by Leonardo Da Vinci (1486 - 1490)
The Italian Minister of Culture Alberto Bonisoli argued that letting France host a major show on Leonardo would "put Italy on the margins of a major cultural event.”
We should expect to see the Italian Leonardos, and amongst them "St. Jerome in the Wilderness" in Paris next Fall but, given the complicated diplomatic relations between France and Italy lately, who knows.
