Trials in England noted in the Gascon rolls

Guilhem Pépin (GP) in discussion with Anne Curry (AC), Simon Harris (SH) and Philip Morgan (PM), August 2015

GP: Among the trials taking place in England mentioned in the Gascon Rolls the most interesting example is the trial at Westminster, opposing Augerot de Saint-Pée against and James Hersage because the latter had obtained for life the lordship of Gamarde in 1438.  Augerot de Saint-Pée was a Basque noble from Labourd and represented there two Gascon lords ...

Making maps

Research materials on this site include a map displaying the political geography of medieval Aquitaine. While a useful resource in its own right, the map is difficult to overlay directly onto a user interface for various reasons:

* It is based on IGN maps, which use the Lambert projection, while in general (as previously discussed), we tend to use WGS-84. This leads to variations that are individually quite small, but visible in aggregate.
* It is a raster image (even ...

Visualising spatial data

In earlier posts in this series, we covered the geocoding of French locations and discussed the shape of the resulting dataset. To recap briefly:

  • Place entities are resolved into a geographic point. We do not at this stage consider the boundaries or area of a given region; we simply look up the centrepoint of the region in question in a large lookup table and, metaphorically, stick a pin in the map at that point.
  • The coordinates of each ...

    Interpreting geocoded data

    In the first post of this series, we covered the geocoding of entities in metropolitan France using INSEE data and entity data provided by expert indexers. 

    This process rapidly generates a large number of data points. Even though the currently published Gascon Rolls contain only a subset of the full dataset, there are already many thousands of unique entities encoded into the XML. A large subset of ...

    First steps in geocoding

    As part of the calendaring process, historians working on the Gascon Rolls routinely identify and encode a variety of types of entity: people, places, things, entry type and so forth. This information, whilst useful in itself, may be considered most useful when placed in a broader aggregate context. How did things change throughout the life of this foothold of English royalty in France? Did the focus move over time, from one town to another, or from one wealthy family to ...
