The Unconscious Patient (Sense of Smell)Credit:The Leiden Collection, New York Four of Rembrandt’s earliest paintings are to be reunited for the first time in centuries after one was discovered in a cellar, as the Ashmolean Museum announces the hunt is still on for one final missing work.The quartet, four-fifths of the “Five Senses” series, are to go on public display in the Oxford museum, after “Smell” was sensationally rediscovered last year.It will now go on public show alongside Hearing, Touch and Sight for the first time, with as experts say the missing Taste could still be “languishing in someone’s attic” somewhere in the world. The Stone Operation (Sense of Touch)Credit:The Leiden Collection, New York The Three Singers (Sense of Hearing)Credit:The Leiden Collection, New York The paintings were created around 1624-5 when the artist was still a teenager, and depict the five senses – a popular allegorical theme of the day.Each picture shows three figures depicting a sense, with Sight showing a squinting woman trying on a pair of spectacles and Hearing showing three singers.Smell, long thought missing, was discovered lsat years in the basement of a New Jersey home in the United States, offered at auction for just $500-800 and thought to be by a minor 19th century painting by an unknown artist. But eagle-eyed European collectors spotted its potential, sparking a bidding war which raised the price to $870,000.The painting was eventually bought by the the Leiden Collection, New York, and restored, being attributed to Rembrandt not least because his monogram was on the canvas.The panel was unveiled to the public at the TEFAF art fair in Maastricht earlier this year, and is now united with its series at the Ashmolean. An Van Camp, curator of Northern European art at the Ashmolean Museum, said: “These earliest of paintings by Rembrandt are fascinating in what they tell us of the young artist’s abilities and his immaturity.“The paintings show that at the age of just eighteen, Rembrandt already has a genius for representing human character and emotion, and for packing in amazing amounts of detail into the briefest of brushstrokes – skills that would see him become one of the most celebrated artists of all time.”The fifth painting, Taste, remains lost and possibly destroyed.The Ashmolean is now encouraging visitors to “draw, paint, recreate or just describe” what the painting may look like via its social media channels.
