Trying to cover his tracks, Ptolemy IX put Alexander’s body in a glass sarcophagus instead. It did not work, though. Citizens of Alexandria were furious and could not forget Ptolemy’s unforgivable deed. They started riots. In the end, greedy Ptolemy IX was killed, which served him right.
But, wait, there is even more. While doing my research for web analytics company, I found something else. It seems that Alexander’s body was kept on display till late antiquity. There was one nasty looter related to this story. It was no one else but Roman emperor Caligula who robbed Alexander’s tomb, stole his armored breastplate and wore it in Rome. Well, as we know, Caligula also ended badly.
It was around two hundred of our era when finally emperor Septimius Severus closed Alexander’s tomb to the public. His son, emperor Caracalla was a big fan of Alexander the Great and often visited his tomb during his rule. After that, history loses track of Alexander’s tomb. The details are pretty vague and unverified.
