The queen of the Princes Czartoryski Museum in Krakow is undoubtedly the "Lady With an Ermine," one of the few surviving portraits by Leonardo da Vinci (1452-1519).

This gentle lady is now receiving royal treatment, in a gallery of her own, at the Yokohama Museum of Art. She is accompanied by a fine selection of paintings, prints and some remarkable objets d'art rarely before seen in Japan.

This is a diverse collection, ranging from an early 13th-century French processional crucifix to exotic spoils from the Siege of Vienna, when the expanding Ottoman Empire was finally stopped at the very gates of Christian Europe, in 1683.
