The tradition of building cursus appears to span much of the middle part of the third millennium RCYBC. Cursus remained visible features of the landscape even after they ceased to be built, and some may have served as ritual foci down through the first half of the second millennium RCYBC. * /Rarity:/ Very rare. Cursus are among the least numerous classes of later prehistoric monuments; less than 50 are currently known in England. Although they are widely scattered, the main concentration lies in central and eastern England. * /Diversity (form): /Low. The main features of cursus are fairly uniform throughout the class, and although there is considerable variation in size the distribution seems to be a continuum rather than a stepped gradation. Only two types can at present be discerned on the basis of ground-plans, and even this division places great emphasis on the form of the terminals. * /Period (representativity): /Very high. Cursus represent one of a relatively restricted range of monuments known to represent the third millennium RCYBC. Little is known about the function of cursus, although it is generally accepted that there may be some overlap in purpose with other classes of ritual/ceremonial monument. Assigning scores to these criteria following the system set out in the Monument Evaluation Manual, cursus yield a Class Importance Value of 49. This lies over two-thirds of the way up the range of possible values (max.= 64), reflecting the rarity and antiquity of these monuments. In selecting examples of national importance due consideration must be given to finding sites which reflect the range of sizes known, the variety of different landscape types in which cursus occur, and the geographical spread of the recorded distribution.
