A post on the Medieval Religion discussion group draws attention to a highly critical online article about the repainting of the interior of Chartres Cathedral. The article in question, which has some illustrations, can be seen at

Not having visited Chartres since this project began I am not well placed to comment on the project. A couple of years ago in
Restoration at Chartres I drew attention to criticism and defence of this work as it was then being undertaken, and the couple of comments that attracted indicate the diversity of opinion about the matter. Indeed the second almost anticipates the comments of the author of the recent article.
I am still inclined to favour the renewal of the original scheme, if that can be reliably reconstructed, and the point has been made on the discussion group that given the nature of modern artificial lighting - clearly very different from what was available in the middle ages - that maybe that should be adjusted when teh scheme is finished.
Keeping things as they are in such buildings is tempting, but may well be unhistorical, and little better than managed decline.
