I found another picture of that sundial in Madrid. According to the description the complex contains four sundials and two moondials. It looks like it has a vertical, equatorial, two polars so the ones on the front must be moondials, but I don't know anything about how moondials work. It is still a fascinating work. The link is below.

If I can figure out the angles, etc. I am going to try to make one. Anyone else know more about this dial? Who made it, etc.?
