Dear Robert, Mark and Rafael The inverted five is a common feature in Spanish eighteen century sundials.
The sundial itself seems to be oriented closer to north than east (an inverted calculation will find the exact declination). The fresco paint, finely executed and apparently well preserved, should allow a relatively easy restoration. Finally, the sentence seems to be exclusive of this dial and is unknown to me. Sure, other members of the list can say more about. I am sending to Mr Rafael detailed information of similar restorations I have made (in Spanish). Regards Miguel A.
