Which of the two is situated in the Eyup district of Istanbul, Eyüp Sultan Mosque or Column of Marcian?
Eyüp Sultan Mosque:  The mosque complex includes a mausoleum marking the spot where Eyüp (Job) al-Ansari, the standard-bearer and friend of the Islamic prophet Muhammad, is said to have been buried. Column of Marcian:  The column is not documented in any late Roman or Byzantine source and its history has to be inferred from its location, style and dedicatory inscription.
