From the first time we saw the name Saskia attached to a portrait of Rembrandt's wife (her full name was Saakje van Uylenburgh, but she was always called Saskia), we have found it utterly charming and wondered why it hasn't attracted more fans In this country--she's appreciated by the Brits, who have moved her to Number 392.
