Notes
- 1.
The expressions “retrograde—i.e. clockwise—direction” and “direct—i.e. anticlockwise—direction” refer to an observer in the Earth’s northern hemisphere looking towards the south.
- 2.
Schiaparelli (1997–1998, Vol. I, pp. 41–89) explains that the use of a lunar calendar—such as the Babylonian calendar—in which lunar eclipses can only occur mid-month makes it far easier to understand the Saros cycle.
Clearly enough, this explanation also applies to the Numan calendar, in which the underlying lunar foundation is disturbed only by intercalations. (see Chap. 15).
- 3.
We shall see later on (Chap. 15) how to calculate the occurrence of eclipses within a Saros cycle.
- 4.
An Exeligmos lasts 669 synodic months, or 19,755.971 days; it also lasts 726 draconitic months, or 19,756.057 days.
