This is a complex Celtic art triskelion which combines designs I originally drew on paper with others that I created entirely on my computer, using Adobe Photoshop.

The triskelion is a very ancient design that forms a three-armed spiral.

During the Middle Ages a variation on this pattern was adopted as the symbol of the Isle of Man, which lies between Britain and Ireland in the middle of the Irish Sea.

The Isle of Man was of tremendous strategic importance in those days, since a navy based there could dominate the passage between those two islands. These days it mainly seems to be a nice place to take a vacation.

Here the triskelion is surrounded by a knotwork border and locked in place by wedge-shaped knotwork panels, much like the prongs on the setting for a gem.
