This is from another article on the museum website. It's by the same author as the other one, Keith Fitzpatrick-Matthews, who is the museum curator. So it does seem to be the curator who is in favour of transing the dead.
Emperor Elagabalus referred to Hierocles, a freedman who was a successful charioteer, as his husband. After granting him his freedom, the emperor attempted to have him declared Caesar, a junior partner in rule and intended successor. A second lover, an athlete named Zoticus, was appointed cubicularius (keeper of the bedroom). The ancient sources suggest that Elagabalus also married him and three other men in addition to his official husband, Hierocles; the historian Cassius Dio refers to the emperor’s relationships with these four other men as adultery, showing that the marriage to Hierocles was treated as a serious legal matter. If they were alive today, we would probably think of Elagabalus as transgender, as he reportedly asked whether a surgical procedure could make him female.
