English: Around 56 examples of the so-called Z-Rod & Double Disc design can be seen on Pictish Standing Stones (around 1200 to 1500 years old) in situ in NE Scotland or in (mainly) Scottish museums; making it one of the most numerous. Although described as a "Z", this shape is, in fact, the reverse of a Z. The general pattern is this reversed Z overlaying two interconnected circles. Many of the circles (or discs) have additional concentric circles and the arms of the "Z" have variants of flame type patterns or finials.
