This article is a result of a survey of rock art sites in the Northern Mountains of Oman undertaken in Spring 1975 by C. F. Clarke and myself. It is not intended as a full report on the rock art but will serve to illustrate the stylistic and iconographic variation found within one part of the content of the art, the anthropomorphs, and also indicate the method of inquiry used in this survey. Therefore specific reference to particular sites or examples will not be made, but different examples will be illustrated in photographs and sketches. The general background to this study of Omani rock art and the problems inherent in this (and any) study of the rock art have been published elsewhere. Therefore I will not expand further on this beyond noting the major characteristics of the art so far discovered: The art is found mainly on the steep limestone walls in the narrow wadis of the Jebel Akhdar. It is usually condensed into sites, which vary greatly in size and complexity, but isolated drawings are sometimes found on boulders and tracks.
