The general distribution of the rock art sites in Morocco is indicated in this report. The vast majority are situated in southern Morocco, in the region of the River Draa and further south. One important exception is the High Atlas mountain range. The location of these sites is shown to be fairly standardised. Four different groups of engravings are identified, based on technique and theme. In the absence of any direct dating of the engravings, these groups can only be placed in a relative chronological order, using dates known for climatic conditions and the introduction of animals or objects. A problem concerns the reliability of these ‘known’ dates, often based on extrapolation from dated information from neighbouring countries. Two recent excavations close to rock art sites have yielded C14 dates for population presence in the area without advancing knowledge on the date of the rock art. The reason for sites’ geographical situation in the landscape can probably be surmised reasonably accurately, but the interpretation of this art remains largely a matter of speculation and intelligent guesswork. Current projects aimed to advance knowledge of the age of the art are described.
