Unicursal hexagram is a hexagram that can be drawn in a continuous stroke, rather than the usual one composed of two overlapping triangles. The hexagram can also be drawn in a circle with each vertex on the circle. It is often drawn in the form of overlapping strokes to form a knot. Unicursal hexagram appeared in the hexagram mysticum theory written by Blaise Pascal in 1639.

In mystics, unicursal hexagram is mainly found in the Thelema sect of Alester Crowley. The five petaled rose representing the pentagram is decorated in the middle of the hexagram in a stroke. This symbol is synonymous with the Egyptian Cross and the rose cross, representing the connection between the small universe and the big universe.
