Sacred Geometry: A Primer

The double square is today's orthogon, as might be inferred by the name, is a rectangle made of two squares. There are multiple ways to construct it, this way starts off with the square, building to the diagon, and then to the sixton.

As with the other orthogons, take the arc up from the diagonal of the sixton. Repeat on the opposite side and cap off the double square.

The lines from other orthagons are ofcourse not required to be in the double square, they are however, useful in composition of a piece. More on that to come.
