Chloé Nelkin reviews the exhibition Leonardo da Vinci: Painter at the Court of Milan, National Gallery, London, on view through February 5, 2012.

Nelkin writes that "The sensational and unprecedented loans and the amassing of these works is something that will, in all likelihood, never be attempted again. Nearly every surviving painting from Leonardo’s Milan period is exhibited including nine of his own works plus around 60 preparatory studies."
