According to China News, the owner of the tomb was identified in 2011 as Liu Fei (169BC-127BC), the first king of the independent kingdom within Han Dynasty Jiangdu. He was the half-brother Han Dynasty's Emperor Wu, who ruled between 141BC and 972BC.

Zhang Fan, a curator, said the artifacts have shown an "almost modern appreciation for the body's needs and wants," adding that both "could be worn and used."

"Useable bronze dildos are still relatively rare finds, though far from unheard of, and they are occasionally found in elite tombs... it's not clear if they were designed for men or women... though the phallus without the ring form was likely for a man since it was found in a king's tomb," Zhang said.

Although the items were never open for public display, the rare artifacts are set to be featured at the upcoming exhibition called Tomb Treasures at the Asian Art Museum in San Francisco, California, between Feb. 17 and May 28, the Mirror reported.

The exhibition will display over 160 artifacts from the Han Dynasty, including luxurious ornaments, worship items, a huge basin used for bathing, a ceramic urinal, a working stone latrine with arm rest, to name a few.

"This exhibition underscores how connected we really are to the past, that we share the same passions across time and culture," Jay Xu, director of the Asian Art Museum of San Francisco and a co-curator for "Tomb Treasures," said.
