Went to a superb talk tonight from Chris Fleet, Map Curator at the National Library of Scotland, on how maps have been used (and misused) over the centuries. Big takeaway is that maps always depend on “ambition and audience”- there’s always a person behind them with a purpose, if not an agenda. Even OS maps omit things due to priorities or simple time constraints. (It strikes me too that cartography could make for a very tidy detective game; so many reasons a map might tell conflicting or partial truths, or subtly shift from one printing to the next!)
