To draw a unicursal figure is defined by tracing all the part of the closed loop forming some kind of picture without taking a pen apart from a sheet of paper on which the picture is drawn. Additionally, you cannot retrace the line already traced.
The unicursal hexagram is a hexagram or six-pointed star that can be traced or drawn unicursally, in one continuous line rather than by two overlaid triangles. The hexagram can also be depicted inside a circle with the points touching it.
English author and occultist Aleister Crowley's adaptation of the unicursal hexagram placed a five petaled rose (symbolizing the Divine), in the center, the symbol as a whole making eleven (five petals of the rose plus six points of the hexagram), thought by some as the number of divine union. It is used in the Greek and Hindu mythologies as a symbol of dedication to the divine rulers.
A unicursal hexagram can also allegedly be seen as a symbol of the solar system in some Pagan philosophies, with the central intersection representing the sun and the outer intersections and points representing the celestial bodies.
