Here’s a cute map, c1608, of the area of South Touraine between La Haye (Descartes) to Azay. The early C17th spelling of place names is of interest as are the lack of details of roads but the significance of rivers and bridges.
The image is an extract from the online map Tvronensis dvcatvs et confinivm Galliae Celticae descriptio created by Abraham Ortelius and Jan Baptist Vrients. It is online courtesy of the National Library of Australia (Australia TROVE). You can view the full map here and then using the tools at the top of the screen you can focus on the area of the Touraine which is of interest.
