Harry Tzalas on legendary stories in Alexandria about the Throne of St. Mark

I have now gone trough some 20 relations of travellers from the 15th to the 19th century mentioning the throne of St. Mark in the old Coptic church that still stand in Alexandria and where their patriarchs are buried. Some say that the throne is very old made of wood and in a derelict condition, some other say that it is covered with coloured marble [opus sectilae]; when I have some free moment I will make a list of these travellers. The fact is that the last evidence we have of a church and a martyrium of St. Mark on the Eastern Coast of Alexandria if the Plan of Simancas made in 1603 after that it is only the Coptic church in the centre of the walled city that is shown as such.
