Dan Moody, a developer of online map services, plans to reveal some images from his Digital Mappa Mundi, a project which he has been working on for the last two years.

These images are redrawn, multi-coloured, layered versions of the original Hereford Mappa, with in-depth research supporting each feature of the images he has drawn. Did you know that Hereford’s famous bonnacon was first described by Aristotle? Have you noticed that the image of Jerusalem conceals a mandala of the Christian universe?

Dan will show how digital resources can be used to provide fresh insights into the Hereford Mappa, embracing, in particular, its anomalies. He sees these anomalies as a mostly-untapped reservoir of knowledge that can be used by anyone to research the Mappa’s background and the designers’ intentions.

This event is part of the Life & Learning programme and will take place in College Hall. Tickets cost £8 (free to cathedral volunteers) – booking is essential via the Cathedral Library on 01432 374 225/6 or by emailing [email protected]
