The exhibit will reopen Feb. 18 with a full complement of mummies and more ancient artifacts from the Tarim Basin in the autonomous Xinjiang Uyghur region of China, the University of Pennsylvania Museum of Archaeology and Anthropology said.
The artifacts are part of "Secrets of the Silk Road," which opened last Saturday. The exhibit had traveled to museums in California and Texas without issue but the Philadelphia museum was asked to gut its display.
Museum spokeswoman Pam Kosty did not say what sparked China's change of heart but said the initial delay was the result of a miscommunication.
"We had extraordinary help from the Chinese Embassy and Chinese officials to make this happen," she said.
The current exhibit will close Sunday so many of the original displays can be installed. It will reopen Feb. 18 and run through March 15. The exhibit will continue March 17-28 without the mummies.
"We are delighted to be able to present the complete range of this spectacular material," said Richard Hodges, the Williams Director of the Penn Museum.
The exhibit's main attraction is a nearly 4,000-year-old, pristinely preserved mummy from far western China, whose flaxen hair and eyelashes are still intact. A well-preserved mummy of a baby, along with vibrantly colored burial trappings of a third mummy, will be among more than 100 ancient objects featured, including pottery, masks, jewelry and coins.
The mummies are particularly fascinating because they have Caucasian features, proving that populations migrated eastward from Europe and brought their customs and skills with them.
Other artifacts include clothing, fabrics, wooden and bone implements, and even preserved foods such as a wonton, spring roll and fried dough. Victor Mair, a Penn professor of Chinese language and literature, has been researching and leading expeditions in the area for more than 20 years and helped develop the exhibit.
