The National Museum of Ireland’s natural history collections include a range of large format artworks, many of paleontological subjects, which were painted by George Victor Du Noyer, the celebrated nineteenth-century geologist, antiquarian, and artist who worked for both the Ordnance Survey of Ireland and the Geological Survey of Ireland (GSI). Letterbook references in the archives of GSI indicate that most, if not all of these, were commissioned by Joseph Beete Jukes, director of the GSI, for different public lecture series. The artistic qualities of the work suggest they were done at speed. However, they also are designed to be seen from a distance within a lecture hall, so an apparently crude technique is appropriate to the purpose. In effect, the watercolor paintings in this series are the PowerPoint presentation of the 1850s.
