Did the Vatican Ruin the Sistine Chapel Frescoes?

One of the most unforgettable spiritual and artistic experiences I’ve encountered in my life happened in the Sistine Chapel years ago. Straining my neck as fellow tourists did the same, I looked up at Michelangelo’s ceiling frescoes in awe—both at the wondrous expression of faith and at the sheer magnitude of human achievement. When I learned that my very breath and perspiration could contribute to the slow destruction of the frescoes, I felt sad. However, when I read Art Watch UK’s accusation that the Vatican undertook a 20-year restoration project of the frescoes “in full knowledge that the stripped-down bare fresco surfaces would thereafter be attacked by atmospheric pollution unless given some other protective covering” (which has not yet happened), I felt rage over the local mismanagement of a global cultural treasure. Did the Vatican ruin the Sistine Chapel frescoes?


In the first part of a series, Art Watch UK lays it out plainly from the beginning: “The Vatican authorities are in conservation crisis today because they stripped the Sistine Chapel frescoes bare in the 1980s and 1990s. They did so against material and historical evidence that Michelangelo had finished off his frescoes with additional glue or size-based a secco painting.” I’ve watched documentary films about the restoration and read plenty of books with generous “before and after” images (such as the one above) all praising the restoration as removing centuries of grime and dirt that stood between modern viewers and how Michelangelo himself saw the frescoes and wanted posterity to see them. After the dimness of the “before” pictures, the “after” images seemed like sunshine flooding into the chapel—a time machine carrying us back to the Renaissance itself.

However, Art Watch UK argues that the “brighter is better” adage is anachronistic, something we accept today but was not accepted in Michelangelo’s day. Citing (with a photograph) Marcello Venusti ‘s1549 copy of Michelangelo’s Last Judgement “which was made not only within Michelangelo’s lifetime but also met with his approval,” they contend that the original frescoes were meant to be darker in overall tone. I’m reminded of a similar, more recent restoration fiasco involving Thomas EakinsThe Gross Clinic. Years after the artist’s death, overzealous conservators stripped away darkening varnishes applied by Eakins to reveal the brighter colors beneath that were more in line with the Impressionism then en vogue. Even when Eakins’ widow, painter Susan Macdowell Eakins, swore that her husband intended the darker tone, her voice when unheeded until the 21st century, when modern restoration efforts returned the painting through archival research to something approximating its original look.

The Art Watch UK piece indicts not just the Sistine Chapel conservation effort, but also the entire conservation world. “Ironically, the ‘cleaning’ of the ceiling, which arguably constitutes the greatest single restoration calamity of the 20th century, occurred at a time when picture restorers had skillfully rebranded themselves as safe, scientifically validated ‘conservators’ of all that is valuable,” they write, “even though Kenneth Clark had recently admitted to having founded the National Gallery’s science department in the late 1930s in order to dupe the public and wrong-foot restoration critics.” Thus, conservation itself becomes an elaborate con game, with, in this case, the Vatican as the dupe. “The authorities at the Vatican seemed quite oblivious of the ease with which even the most modest restorations can escalate into dangerous and irreversible treatments,” Art Watch UK acidly accuses.

The article does step back from that hard-hitting position by adding in an appendix Kathleen Weil Garris Brandt’s more level-headed point that “the conservation of any work of art is doomed to failure unless equal emphasis is given to its past and its future vicissitudes…Scientists and historians worry that conservators can be too ready to intervene, too impatient of prior tests, and insufficiently heedful of future dangers. Conservators should hesitate to go where even angels fear to tread (or clean, in this case) unless they follow the oath to do no harm, i.e., make no permanent changes that later generations can’t undo in the light of additional information. I’ve heard enough conservation success stories full of patient, thoughtful respect not just for the work, but also for all those who wish to enjoy it now and hereafter to believe that this possible abomination is an aberration—malpractice on an epic scale that deserves note but not something that should bring down a whole discipline.

Creeping papal infallibility over the past couple of centuries threatens to go beyond matters of faith into all fields of human knowledge, but it seems time for the Vatican, in at least this matter, to admit it goofed. The main point of asking the question of whether the Vatican ruined the Sistine Chapel frescoes isn’t to assign blame, but rather to salvage these treasures before it is too late. The first step, however, is admitting that something must be done quickly. The truth, as always, will set them free.

Why "nuclear pasta" is the strongest material in the universe

Through computationally intensive computer simulations, researchers have discovered that "nuclear pasta," found in the crusts of neutron stars, is the strongest material in the universe.

  • The strongest material in the universe may be the whimsically named "nuclear pasta."
  • You can find this substance in the crust of neutron stars.
  • This amazing material is super-dense, and is 10 billion times harder to break than steel.

Superman is known as the "Man of Steel" for his strength and indestructibility. But the discovery of a new material that's 10 billion times harder to break than steel begs the question—is it time for a new superhero known as "Nuclear Pasta"? That's the name of the substance that a team of researchers thinks is the strongest known material in the universe.

Unlike humans, when stars reach a certain age, they do not just wither and die, but they explode, collapsing into a mass of neurons. The resulting space entity, known as a neutron star, is incredibly dense. So much so that previous research showed that the surface of a such a star would feature amazingly strong material. The new research, which involved the largest-ever computer simulations of a neutron star's crust, proposes that "nuclear pasta," the material just under the surface, is actually stronger.

The competition between forces from protons and neutrons inside a neutron star create super-dense shapes that look like long cylinders or flat planes, referred to as "spaghetti" and "lasagna," respectively. That's also where we get the overall name of nuclear pasta.

The researchers' computer simulations needed 2 million hours of processor time before completion, which would be, according to a press release from McGill University, "the equivalent of 250 years on a laptop with a single good GPU." Fortunately, the researchers had access to a supercomputer, although it still took a couple of years. The scientists' simulations consisted of stretching and deforming the nuclear pasta to see how it behaved and what it would take to break it.

While they were able to discover just how strong nuclear pasta seems to be, no one is holding their breath that we'll be sending out missions to mine this substance any time soon. Instead, the discovery has other significant applications.

One of the study's co-authors, Matthew Caplan, a postdoctoral research fellow at McGill University, said the neutron stars would be "a hundred trillion times denser than anything on earth." Understanding what's inside them would be valuable for astronomers because now only the outer layer of such starts can be observed.

"A lot of interesting physics is going on here under extreme conditions and so understanding the physical properties of a neutron star is a way for scientists to test their theories and models," Caplan added. "With this result, many problems need to be revisited. How large a mountain can you build on a neutron star before the crust breaks and it collapses? What will it look like? And most importantly, how can astronomers observe it?"

Another possibility worth studying is that, due to its instability, nuclear pasta might generate gravitational waves. It may be possible to observe them at some point here on Earth by utilizing very sensitive equipment.

The team of scientists also included A. S. Schneider from California Institute of Technology and C. J. Horowitz from Indiana University.

How a huge, underwater wall could save melting Antarctic glaciers

Scientists think constructing a miles-long wall along an ice shelf in Antarctica could help protect the world's largest glacier from melting.

Surprising Science
  • Rising ocean levels are a serious threat to coastal regions around the globe.
  • Scientists have proposed large-scale geoengineering projects that would prevent ice shelves from melting.
  • The most successful solution proposed would be a miles-long, incredibly tall underwater wall at the edge of the ice shelves.

The world's oceans will rise significantly over the next century if the massive ice shelves connected to Antarctica begin to fail as a result of global warming.

To prevent or hold off such a catastrophe, a team of scientists recently proposed a radical plan: build underwater walls that would either support the ice or protect it from warm waters.

In a paper published in The Cryosphere, Michael Wolovick and John Moore from Princeton and the Beijing Normal University, respectively, outlined several "targeted geoengineering" solutions that could help prevent the melting of western Antarctica's Florida-sized Thwaites Glacier, whose melting waters are projected to be the largest source of sea-level rise in the foreseeable future.

An "unthinkable" engineering project

"If [glacial geoengineering] works there then we would expect it to work on less challenging glaciers as well," the authors wrote in the study.

One approach involves using sand or gravel to build artificial mounds on the seafloor that would help support the glacier and hopefully allow it to regrow. In another strategy, an underwater wall would be built to prevent warm waters from eating away at the glacier's base.

The most effective design, according to the team's computer simulations, would be a miles-long and very tall wall, or "artificial sill," that serves as a "continuous barrier" across the length of the glacier, providing it both physical support and protection from warm waters. Although the study authors suggested this option is currently beyond any engineering feat humans have attempted, it was shown to be the most effective solution in preventing the glacier from collapsing.

An example of the proposed geoengineering project. By blocking off the warm water that would otherwise eat away at the glacier's base, further sea level rise might be preventable.

But other, more feasible options could also be effective. For example, building a smaller wall that blocks about 50% of warm water from reaching the glacier would have about a 70% chance of preventing a runaway collapse, while constructing a series of isolated, 1,000-foot-tall columns on the seafloor as supports had about a 30% chance of success.

Still, the authors note that the frigid waters of the Antarctica present unprecedently challenging conditions for such an ambitious geoengineering project. They were also sure to caution that their encouraging results shouldn't be seen as reasons to neglect other measures that would cut global emissions or otherwise combat climate change.

"There are dishonest elements of society that will try to use our research to argue against the necessity of emissions' reductions. Our research does not in any way support that interpretation," they wrote.

"The more carbon we emit, the less likely it becomes that the ice sheets will survive in the long term at anything close to their present volume."

A 2015 report from the National Academies of Sciences, Engineering, and Medicine illustrates the potentially devastating effects of ice-shelf melting in western Antarctica.

"As the oceans and atmosphere warm, melting of ice shelves in key areas around the edges of the Antarctic ice sheet could trigger a runaway collapse process known as Marine Ice Sheet Instability. If this were to occur, the collapse of the West Antarctic Ice Sheet (WAIS) could potentially contribute 2 to 4 meters (6.5 to 13 feet) of global sea level rise within just a few centuries."
