________________________________________________________________The article describes the preliminary results of an archaeological survey of a protest camp occupied since 1999 in Derbyshire, England, and reflects briefly on the role of archaeology in researching contemporary activism and protests. The camp is structured by the everyday activities involved in living in the landscape, by the 'manufactured vulnerability' created using characteristics of the environment to contest an attempted eviction, and the public statements of protest that symbolise the campaign to the wider world. Through its longevity and the high profile of the wider anti-quarry campaign the camp is now a key element in the history of its landscape, and it is on these terms that it became the subject of archaeological research. ________________________________________________________________ Résumé: L'article décrit les résultats préliminaires d'une enquête archéologique menée dans un camp de protestation occupé depuis 1999 à Derbyshire, Angleterre, et reflète brièvement le rô le de l'archéologie dans des recherches concernant l'activisme contemporain et les protestations.

SYNOPSISThe years between 1660 and 1800 were important ones in the study oflight. For most of the period the work, especially in this country, was largely dominated by the theories advanced by Newton; unfortunately the protagonists of these theories were much more rigid in their approach than was Newton himself. There was, in effect, almost a century of 'rear-guard actions' to maintain the corpuscular theory at all costs.Fortunately, the advance of geometrical optics and the design of optical instruments was not retarded to a very great degree by this partisan approach. The workers in these fields were not, as a rule, too involved in speculation, and worked largely empirically.Some of die modifications to the original corpuscular theory are interesting. Attempts were made to explain, with varying degrees of success, total internal reflection, dispersion, interference effects, diffraction and phosphorescence. Considerable speculation about the velocity of light occurred in connection with these topics. At the same time, wave theories never completely died out and, although they were not developed until the early part of the nineteenth century, their influence was felt even in this country.T H I S was an important and interesting period in the study oflight but, in some respects at least, it proved to be largely a negative one. Two theories were in conflict, and some of the elaborations of the basic ideas were very complex and ingenious, but there was, at the time, no critical experiment to decide between them. This, of course, is not an unusual state of affairs except that the period involved was uncommonly long, being about two hundred years in all.
