- The Latin text is that given at â€œThe Electronic Grossetesteâ€, www.grosseteste.com
- In the Latin text, Grosseteste defines the heat as â€œunivocusâ€, and therefore I translated it as â€œunivocalâ€, in the sense of â€œbeing of a single kindâ€
- In the Latin text, there is the term â€œageneratixâ€, which seems quite odd. I translated it as â€œsourceâ€. See also, A.C. Crombie, Science, Optics and Music in Medieval and Early Modern Thought, Continuum International Publishing Group, 1990
- The â€œequinoctial circleâ€ is the great circle on the celestial sphere midway between the celestial poles. Then we have the two tropical circles. One of them is called the Tropic of Cancer. When this circle was named, the Sun passed through the Zenith at its latitude, when was also in the direction of the constellation Cancer (Latin for crab). However, this is no longer true due to the precession of the equinoxes. The word "tropic" comes from the Greek â€œtropeiâ€, meaning â€œturnâ€, referring to the fact that the Sun appears to â€œturn backâ€ on the solstices
