Thid thesis concerns pre-Roman religion in Gaul, taking as its starting point Caesar's De bello Gallico. Caesar's account of the Gauls and their religious customs is compared with the accounts of Lucan, Pliny the elder and Ammianus Marcellinus. These are also compared to, and contrasted to, the archaeological evidence. There is some discussion of the nature of the common interpretations of this evidence. The concept of 'the Celts' is touched upon, since much of the relevant evidence has, in our time, been thought of as Celtic.

In this essay I investigate how the Roman colonization (around 50 BC to 400 AD) affected the Celtic religion. I inquire which operators that were behind these changes and under what circumstances they happened. I take a closer look on three places in Gaul and one place and one area in Britain. In my study of these places I see that it was the elite of the Celtic societies who together and under pressure from Rome made these changes. The religion and gods did not change; instead the ritual ceremonies changed to fit into something that Rome thought was right.

This essay concerns the Celts during the Iron Age, and their ritual practice in human sacrifice. The method applied is an eclectic historic-critic reading of the few classical sources that exist together with archeological material and scholars conclusions of literal sources and archeological material. The hypothesis is that human sacrifice in the Celtic realm not is to be seen as a primitive act of violence, but that it filled a social function to preserve society and the Celtic way of life.The question this essay strives to answer is Which function/s do human sacrifice fill in a Celtic context during the Iron Age? The question is analysed with the aid of Radcliffe-Brown?s and Catherine Bell?s theories on ritual, as well as Malcolm Chapman?s postmodern ideas of the conception of the Celtic. The conclusion of the essay is that the prime functions of Celtic human sacrifice are to preserve society and the Celtic social way of life, combined with an aim to eliminate disturbing elements in that same society, such as crime and individuals who did not fit in to the social community..
