For anyone interested in Coptic history there is an article in the current issue of the Biblical Archaeology Review by Dorothy D. Resig entitled “Crossing the Holy Land:”
One of the seven cities in Revelation; the possible site of Zechariah’s tomb; the Avenue of the Sphinxes in Luxor; and a Coptic monastery in the Egyptian desert. What do all they all have in common? Ancient churches have recently been excavated at each of them. Each has its own story to tell, including a case of some beautiful but tragic mosaics.
