That leaves a nice pattern on the face of the dial. Why not just have two gnomons, each originating from the hour line junctures. Sent from my iPhone

The wide gnomon would, I think, be some form of inclined surface with the east and west sides acting as styles. Because it's an underslung configuration, in my mind's eye the part of the wall below the gnomon is relevant - equivalent to the 'noon overlap' seen in the horizontal examples, so with hour lines something like the graphic below (here with gnomon drawn semi-transparent so that the dial face can be seen.) If I'm imagining it correctly, that is. I'm asking about it on the list because I've never seen this configuration of sundial, so I'm after examples of how they've actually been laid out.

All I can think of is the north facing dial but I guess that’s not what you’re talking about.

I'm happy to report that between them, those responses confirmed my idea of how underslung gnomons work. Now turning to the more specific case of a vertical dial, and clarifying my original posting, does anyone know of actual examples of vertical dials with wide underslung gnomons?
