Adrian Henry Timothy Knottesford Fortescue,
The Orthodox Eastern Church
(1907)
“ No other building has anything like as much importance in the history of architecture as the Hagia Sophia. Other great churches are, each of them, only one out of many of the same kind; this church rose, after humble and tentative efforts, as the one great example, the model on which a whole style was founded. It is not the daughter, it is the mother, of Byzantine architecture. Nothing that went before can be compared to it, and afterwards for centuries, down to our own time, Byzantine artists have had before them this one model, copied and imitated by all, but never rivalled. ”
