Mesopotamian Cosmic Geography represents the main part of my first decade of study as an assyriologist. The book began its life as a Ph.D. thesis of the same name under the supervision of Professor W G. Lambert of the Univer- sityof Birmingham. After completion of the Ph.D. thesis in 1986, I continued to collect materials relevant to the study of Mesopotamian views of cosmography with the intention of revising the thesis as a book in the early 1990s. The book Mesopotamian Cosmic Geography presents this revised, more mature examina-tion of the topic.
