This week , scientistsdiscovered something altogether newabout one of Picasso ’s most famous works : It was covering up another painting . But this was n’t the first unknown work discovered beneath a illustrious work over the past few years . Thanks to unexampled technical school , dozens of lost plant are re-emerge .

artistry preservation has always taken the skills of a scientist — and an expertise in chemistry — but these days , newfangled methods of conservation are transmute the subject area . For instance , to determine out whether a painting was made before 1945 , scientists can test the canvas fortwo radioactive isotopesthat are singular to the atomic bombs released after 1945 . Or , for older painting , they can practice Terahertz spectroscopy , or simply infrared imaging , so find out what lies below the top coat .

Below , we submit a look at some of the most incredible discoveries of the retiring few year — but first , here ’s a bit more about this newly - observe mystery house painting .

The Man Hidden Beneath Picasso’s Blue Room

Picasso was just 19 in 1901 , when he painted The Blue Room , one of his most well - known house painting . If it looks melancholy to you , that ’s because it is — this is a picture from his Blue Period , animate by the suicide of a close Quaker in 1901 and the severe depression that followed . Here ’s what the house painting looks like :

But it turn out that The Blue Room was n’t the work Picasso set out to paint . In fact , it was a 2nd try ( or possibly even third , for all we have a go at it ) . Using infrared scanning and multi - spectral imaging technology , scientists in D.C. have been capable to nibble together a glimpse at what lies beneath this iconic oeuvre : A gentleman in a bow - tie , whose identity remains unknown .

curator have muse that this older study exist for X , but imaging technology has only gotten right enough over the retiring few years to discover precisely what was there . Next up : estimate out who he is .

The Beached Whale That Vanished Into Thin Air

A conservator working on this 17th one C painting by the Dutch lord Hendrick van Anthonissen was choke about her commercial enterprise admit off a layer of varnish when she noticed something odd : The faint outline of a soul standing on the horizon of the ocean . heedful body of work under a microscope revealed that this figure had been put up on something — a beached whale that had been paint out of the picture .

But why ? “ It ’s possible that the whale was removed because the presence of a dead animal was see nauseating – or perhaps without the giant the picture was more marketable,”she explains .

The Woman Van Gogh Painted Over

Van Gogh , like plentifulness of other penniless creative person , reused canvases — which means that he in all likelihood painted over passel of fail deeds in his time . This one wasdiscoveredusing gamy - intensity X - ray from a molecule accelerator , which allow scientist to detect what types of pigment were layer at an atomic level .

The Da Vinci That Was Whitewashed For 500 Years

Restorers were work on the Sforza Castle when they discovered a lost Da Vinci mural under almost 20 layers of whitewash . Below all that key was a monolithic mural depicting tree diagram that grew from the walls up onto the cap , where they mold a arbour of branches . Now , the painting is being carefully regenerate to its former gloriole — you may keep an eye on the advance here .

The Roman Fresco Discovered In the Louvre

Giampietro Campana was a painter and collector of Roman artistry in the 19th hundred — not all that long ago , by most standards . But scientists recently let out that beneath one of Campana ’s own frescos , which fall in the Louvre , was lurk an graphics M of years older .

Using Terahertz spectrographic analysis — basically , the same eccentric of radiation sickness they use to take your full body scan at the airport — scientists realized that there was a Roman fresco mess about beneath Campana ’s late work . “ We could not conceive our eyes as the trope materialized on the screen,”said main investigator J. Bianca Jackson . “ Underneath the top painting of the folds of a man ’s tunic , we saw an eye , a nose and then a mouth come out . We were seeing what belike was part of an ancient Roman fresco , thousands of long time old . ”
