Everyone has seen that astronomical clock in the bottom left corner of the Rosettes foldout. That is what Professor Brumbaugh called it, but in reality, it is not a clock but a small volvelle—a medieval tool used for astronomical and astrological calculations.
We see that it is a small sphere with two concentric circles. Between the two circles are eight groups of three lines each. Each line represents 15 degrees or one hour, resulting in 360 degrees or 24 hours.
Inside, we see a triangle formed by three small circles connected by two lines. What that represents is the astrological aspect of the trine. A small circle represents the Sun, and the other two represent the Moon. The Sun joins the Moon in the two hemispheres at a distance of 120 degrees.
On folio f67v2, where the most important astrological aspects are depicted, the trine is the one located in the upper left. It consists of those three small heads joined in a triangle.
