It is said to be the work of local villages in the 18th century, but I personally doubt this. The type of horse depicted is not the kind of horse that was common in those times - the Shire horses were commonly used for farming and for battle. This horse has many Arab features and has the legs of a horse bred for speed. I think that the original outline was laid down well before the 18th century. How long before? Somewhere around the 13th or 14th centuries or even earlier?
I used my Nikon D7100 with the 16.0-85.0 mm f/3.5-5.6 VR. I made ten vertical exposures and stitched the panorama in PS CS5 Photomerge.
