A rare sundial you just don't see very often. I believe it's made by French Nicholas Bion during 18th century. On the front of the dial, there are several sets of Roman numerals.I'm sure they are for you to tell the time. You will also see a compass, which helps you to determine the direction. On the reverse side, you will see a list of cities' name with a number following them.
