These eight parameters, often tabulated at hourly intervals serve as the only input needed to characterize an eclipse. One of the most exciting historical examples is the Antikythera Mechanism, an ancient machine that kept track of the date, and the positions of the Sun, Moon, and planets.

“It also predicted eclipses and kept track of upcoming Olympic games,” Jones writes in his book It’s a gloriously intricate piece of ancient technology, likely once very beautiful, and mostly made of bronze.

Alexander Jones, Professor of the History of the Exact Sciences in Antiquity at New York University, says the math is not necessarily that hard, but there’s a lot of it.

“It doesn’t take anything that’s much more advanced than, say, grade school mathematics to do,” he says, “but it would take you working with pencil and paper probably a couple of hours to do a complete calculation.” “You really need to know that the Earth is round, and you need to know where you are on that spherical Earth, because the shadow of the Moon is such a small area,” adds Jones.

The radii of the penumbral and umbral shadows on the fundamental plane are also tabulated as L1 and L2, respectively.

Unfortunately, the subsequent Saros eclipses don’t happen in the same place, but one-third of the way around the Earth.

It takes three Saros cycles for an eclipse to recur in a similar place as the first one—approximately 54 years later.

In fact, people have been watching and counting—making calendars, essentially—for almost as long as they’ve farmed the land.

“Every organized, agriculturally based civilization develops a calendar, because that’s what you need to determine planting times,” says Ramon Lopez, a space physicist at the University of Texas at Arlington.
