I like heraldry. I like the way that a coat-of-arms can be described in so few words, most of them very strange. 'A bend or' for instance. How about: "Or between two Flaunches fracted fesswise two Roundels Sable over all six Guitar Strings palewise throughout counterchanged"? [Sir Paul McCartney]. This leads to my questions: how should the coat-of-arms in the attached photo be described, and whose coat-of-arms is it? The photo was taken in the Praza do Obradoiro. The device is on what I think is part of the Pazo de Xelmírez, and so I suspect that it belongs to the Archbishp Xelmírez who ordered the construction of the building; however, I would appreciate confirmation. I'd like to know what the lower half of the device represents: is it a bridge, or scaffolding?
