OXFORD, England—Two priceless paintings, a watercolor by Dante Gabriel Rossetti and an oil painting by Sir Edward Coley Burne-Jones, have been saved for Britain after being discovered in manuscript curator Jean Preston's Oxford home after she died in 2006 at the age of 77, the Mirror reports. Those works, which Preston's family said will go on display at a museum, weren't the only expensive art found in the house. Two lost 15th-century works by Italian painter Fra Angelico (which the family sold for £1.7 million [$3.8 million]) and a rare edition of the works of Geoffrey Chaucer were also discovered there. "It was like stepping into an Aladdin's cave," said auctioneer Guy Schwinge. "In almost every room there were staggeringly important works of art."
