Donceel and Donceel-Voûte, “The Archaeology of Khirbet Qumran,” p. 12. Donceel-Voûte also refers to “a number of colored stone slabs [at Qumran], carefully cut to be used in pavements of the opus sectile type,” which is apparently the same opus sectile pavement mentioned by Humbert in connection with Ein Feshkha, suggesting that one of the two parties is confused.
