This paper explores Continental contexts for the understanding of taxation in eleventhcentury England. The subject is widely recognized as important but fraught with difficulty. The central idea is the relevance of Carolingian practices of surveying and the keeping of written records for later Anglo-Saxon and Anglo-Norman government. Such a European perspective has been important for Anglo-Saxon historians: one thinks especially of the model emphasizing Carolingian influence on later Anglo-Saxon government advanced by James Campbell and Patrick Wormald. 1 It has also been important for historians of Domesday, when one considers the comparative richness of the Carolingian administrative record, comprising the corpus of polyptychs, plus capitulary material indicating government interest in surveys and list-making. The Carolingian sources have been seen as the best comparanda for the two Domesday volumes and 'satellite' texts, as explored in classic studies by Campbell, John Percival, Henry Loyn and R. H. C. Davis. 2 Are these indications of a shared early medieval culture of surveying and information gathering? There has been awareness that Anglo-Norman administrators came from a world familiar with polyptychs and certain legacies of Carolingian government, though ultimately commentators have placed more emphasis on the distinctiveness of the Domesday record.One should stresss the necessary limits of knowledge on this difficult subject. Firstly, one encounters the dominance of Domesday in the surviving English record. The use of shire and hundredal structures in 1086 is highly suggestive of some administrative continuity from Anglo-Saxon government, but how much should one envisage in respect of written documentation? It was generally harder for Anglo-Saxon material to survive. This is especially shown by particular forms of Anglo-Saxon document which we know to have been widespread, now attested in rare or unique instances, such as certain types of writ. 3 Yet it remains difficult to weigh silences. Secondly, the Carolingian material is relatively extensive, but heavily skewed towards documents produced and preserved by ecclesiastical houses. The
