A Texas astronomer has used science to confirm one of the most famous tales in western literature, the "bright and shining moon" over Lake Geneva that inspired an 18-year-old Mary Shelley to write "Frankenstein; or the Modern Prometheus."
Shelley has long been doubted for her version of events that led to the writing of one of the most beloved Gothic tales in the English language: That she wrote it on a challenge one night in June 1816 during a "waking dream" as the moon shone through her window.
But Donald Olson, an astronomy professor at Texas State University in San Marcos, told Reuters on Monday that the night sky would argue that she was telling the truth.
"Some scholars are very skeptical, they even call her a liar," Olson said. "But we see no reason, either in the science or in the primary sources, to doubt Mary Shelley's account."
Olson has made a hobby out of using the sky to solve the mysteries of many of the world's most famous works of art and historical accounts.
His study of tides in the English Channel forced historians to change the accepted date of Julius Caesar's invasion of Britain in 55 BC, and he used astronomical tables to pinpoint where and when Vincent Van Gogh painted the famous painting alternately known as "Moonrise" and "Sunrise over Saint-Remy."
Shelley first wrote of how she came to write Frankenstein in the preface of the book's 1831 edition, and critics immediately began questioning her story as simply a ruse to sell more books.
The story goes like this: Shelley was staying with her future husband, Percy Shelley, at the Villa Diodati in Switzerland in June of 1816. Also present were Lord Byron and friends Claire Clairmont and John Polidori. Byron challenged all of them to try their hand at writing a ghost story.
WAKING DREAM
Shelley saw the "bright and shining moon" through her window that night and wrote the story while she was in what she called "a waking dream."
The closest account of Byron's challenge comes from Polidori's diary, in which he tells of the party gathering at the Villa Diodati for a philosophical discussion that ended "after the witching hour" of June 16, 1816. The next day he wrote that "the ghost-stores are begun by all but me."
But Olson said there was no record of the challenge itself from any sources other than Shelley's preface, and the assumption has always been made, though not proven, that the challenge and the writing took place early in the morning of June 16.
But he said that had never been confirmed until now.
"We verified when the moon would have shone on her window, which is when she first came up with the idea for the story we know as Frankenstein," Olson said.
The Villa Diodati still stands above Lake Geneva and the room where Shelley stayed is well known. Olson and his researchers made "extensive topographic measurements of the terrain" and investigated "weather records for June of 1816," described by Lord Byron and Polidori as unusually wet and rainy.
On that night, however, "we determined that a bright, gibbous moon would have cleared the hillside to shine right into Shelley's bedroom window just before 2 a.m. on June 16," Olson said.
He said that had there been no moonlight visible that morning, it would have indicated fabrication on her part.
"This indicates her famous "waking dream" that gave birth to Frankenstein's famous monster occurred between 2 a.m. and 3 a.m. on June 16," he said.
"Mary Shelley wrote about moonlight shining through her window, and now we have recreated that night," Olson said. "We see no reason to doubt her account, based on the astronomical data."
Olson's study appears in the October edition of "Sky and Telescope" magazine.

Full Harvest Moon
The full moon of September hit its peak Monday (Sept. 12), thrilling skywatchers around the world who turned out to photograph the Harvest Moon of 2011.
Historically, the Harvest Moon has been a boon for farmers because the moon hangs low on the southeastern horizon and shines bright enough to squeeze in a bit of extra time harvesting crops at night.
That fact was not lost on skywatcher and photographer Jeffrey Berkes outside of Philadelphia, Pa., when he ventured outside with a camera in hand.

NASA Galileo satellite: Sounding Signal on Jupiter's Moon
This graphic and animation show the internal structure of Jupiter's moon Io as revealed by data from NASA's Galileo spacecraft.
The low-density crust about 30 to 50 kilometers (20 to 30 miles) thick is shown in gray in the cross-section.
The newly discovered subsurface molten or partially molten magma "ocean" – also known as the asthenosphere – is shown in red-brown beneath the crust.
This global magma layer is believed to be more than 50 kilometers (30 miles) thick, with the outer part making up at least 10 percent of the entire mantle by volume. The mantle has been colored gold in this graphic.
Io is bathed in magnetic field lines (shown in blue) that connect the north polar region of Jupiter to the planet's south polar region. As Jupiter rotates, the magnetic field lines draping around Io strengthen and weaken.
Because Io's magma ocean has a high electrical conductivity, it deflects the varying magnetic field, shielding the inside of the moon from magnetic disturbances.
The magnetic field inside of Io maintains a vertical orientation, even as the magnetic field outside of Io dances around. These variations in the external magnetic field signatures enabled scientists to understand the moon's internal structure.
In the animation, the magnetic field lines move with Jupiter's rotation period of about 13 hours in Io's rest frame. › See the animation
Io's mantle is made of "ultramafic" rocks, a class of rocks rich in iron and magnesium silicates, which become capable of carrying substantial electrical current when melted. Ultramafic rocks are igneous in origin – that is, formed through the cooling of magma. On Earth, they are believed to derive from the mantle.
Io's ultramafic mantle must have a temperature exceeding 1,200 degrees Celsius (2,200 degrees Fahrenheit) to support rock melting in the asthenosphere. Io's core, about 600 to 900 kilometers (400 to 600 miles) in radius is composed of iron and iron sulfide and shown in a metallic silver hue.
The Galileo mission was managed by JPL, a division of the California Institute of Technology in Pasadena, for NASA.

Cassini radar sees sand dunes on Saturn's giant moon Titan
Image credit: NASA/JPL (upper photo); NASA/JSC (lower photo)Cassini radar sees sand dunes on Saturn's giant moon Titan (upper photo) that are sculpted like Namibian sand dunes on Earth (lower photo).
The bright features in the upper radar photo are not clouds but topographic features among the dunes.
The answer to the mystery of dune patterns on Saturn's moon Titan did turn out to be blowing in the wind. It just wasn't from the direction many scientists expected.
Basic principles describing the rotation of planetary atmospheres and data from the European Space Agency's Huygens probe led to circulation models that showed surface winds streaming generally east-to-west around Titan's equatorial belt.
But when NASA's Cassini spacecraft obtained the first images of dunes on Titan in 2005, the dunes' orientation suggested the sands - and therefore the winds - were moving from the opposite direction, or west to east.
A new paper by Tetsuya Tokano in press with the journal Aeolian Research seeks to explain the paradox. It explains that seasonal changes appear to reverse wind patterns on Titan for a short period. These gusts, which occur intermittently for perhaps two years, sweep west to east and are so strong they do a better job of transporting sand than the usual east-to-west surface winds.
Those east-to-west winds do not appear to gather enough strength to move significant amounts of sand.
A related perspective article about Tokano's work by Cassini radar scientist Ralph Lorenz, the lead author on a 2009 paper mapping the dunes, appears in this week's issue of the journal Science.
"It was hard to believe that there would be permanent west-to-east winds, as suggested by the dune appearance," said Tokano, of the University of Cologne, Germany. "The dramatic, monsoon-type wind reversal around equinox turns out to be the key."
The dunes track across the vast sand seas of Titan only in latitudes within 30 degrees of the equator. They are about a kilometer (half a mile) wide and tens to hundreds of kilometers (miles) long. They can rise more than 100 meters (300 feet) high.
The sands that make up the dunes appear to be made of organic, hydrocarbon particles. The dunes' ridges generally run west-to-east, as wind here generally sheds sand along lines parallel to the equator.
Scientists predicted winds in the low latitudes around Titan's equator would blow east-to-west because at higher latitudes the average wind blows west-to-east. The wind forces should balance out, based on basic principles of rotating atmospheres.
