1927. The main text of this work is written in a manner to be understood in all essentials by the general reader without specialist knowledge. For the same reason the Greek and Latin texts have been furnished with translations, a good means of enabling the author to check his impressions. A large number of the more important texts are presented in facsimile. In obtaining the necessary photographs, rubbings, etc., the author was assisted by several scholars and publishers at home and abroad.
