In the second half of the 19th century, advances in physics, electromagnetic radiation theory, and the optical sciences provoked new thought about the physical as well as the spiritual worlds. Aspects of that thought are revealed in Edvard Munch: Color in Context, an exhibition of 21 prints that considers the choice, combinations, and meaning of color in light of spiritualist principles. Informed by popular manuals that explained the science of color and by theosophical writings on the visual and physical power of color, Edvard Munch (1863–1944) created works that are not just strikingly personal but also are charged with specific associations. Edvard Munch will be on view in the West Building from September 3, 2017, through January 28, 2018. The majority of the prints in the exhibition come from the Epstein Family Collection, the largest and finest gathering of the artist’s graphic work outside of his native Norway. Their holdings are being steadily donated to the Gallery.

Construction crews breaking ground on a new fire and police station north of Denver, Colorado have unearthed a 66-million-year-old triceratops skeleton, sparking a flurry of scientific interest in this iconic herbivore. Diggers working on a site in Thornton — population 137,000 — encountered an immovable object on August 25. One of the workers thought it might be a fossil, so they called the Denver Museum of Nature and Science. Curator Joseph Sertich arrived at the scene and identified the bones as belonging to a triceratops. “This is a pretty small triceratops,” Sertich said in a Facebook Live broadcast from the work site on Wednesday. This fossil is about half the size of triceratops unearthed in Montana and North and South Dakota. “We don’t really know why,” Sertich said.

Vast underwater Roman ruins have been discovered off northeast Tunisia, apparently confirming a theory that the city of Neapolis was partly submerged by a tsunami in the 4th century AD. “It’s a major discovery,” Mounir Fantar, the head of a Tunisian-Italian archaeological mission which made the find off the coast of Nabeul, told AFP. He said an underwater expedition had found streets, monuments and around 100 tanks used to produce garum, a fermented fish-based condiment that was a favourite of ancient Rome. “This discovery has allowed us to establish with certainty that Neapolis was a major centre for the manufacture of garum and salt fish, probably the largest centre in the Roman world,” said Fantar. “Probably the notables of Neapolis owed their fortune to garum.” Fantar’s team started work in 2010 in search of the port of Neapolis but only made the breakthrough find of the ruins stretching out over 20 hectares (almost 50 acres) this summer thanks to favourable weather conditions.
