The Louvre is having what some might call the ultimate Leonardo exhibition in the fall, marking the five hundredth anniversary of his death, which will include his paintings, drawings, and writings. But there is a major snafu: The Italian government is now saying that it will not lend the three major Leonardo paintings from the Uffizi for this event, claiming it would put Italy “on the margins” of this celebratory anniversary. (See brief article below.) Another related article I found says Italy is also citing the fragility of the paintings as a reason to rescind its previous offer of the loans and is reminding France of its unwillingness to send the "Mona Lisa" to other countries for exhibitions. The absence of the Uffizi paintings would create a significant gap in the Louvre exhibition. Will Italy reverse its decision in the coming months?
