LONDON, ENGLAND—The remains of a Roman temple dedicated to the bull-slaying god Mithras, which dates to the third century A.D., are set to be reopened to the public in Bloomberg's new European headquarters, according to a report in The Guardian. Mithraism was a cult religion devoted to Mithras practiced across the Roman Empire from about the first to the fourth centuries A.D. and was especially popular among soldiers. While their beliefs and rituals remain largely a mystery, followers of Mithraism had a complex system of initiation and met in underground temples called mithraea, many of which survive. The London Temple of Mithras was first discovered in 1954 and, for a time, was partially (and poorly) reconstructed for visitors on a nearby car park roof. Now in its original location, the mithraeum will be displayed alongside artifacts uncovered at the site. To read more about Roman Britain, go to “The Wall at the End of the Empire.”
