Picture of and brief caption re the Theodosius obelisk. The Theodosius obelisk was removed from Luxor by the Byzantine emperor Theodosius I in the late 4th century, and now stands in Istanbul's Hippodrome Square, in front of the Blue Mosque. At 19.5 meters in height, the obelisk is in fact incomplete, missing a section at the bottom. No-one appears to know when this was lost or what happened to it.
