Ancient Maya Astronomy

Maya glyph thought to mean 'solar eclipse.'


Without any special tools to bring things into closer view, the ancient Maya watched the skies, studying the stars, various planets, the moon and the sun. They may have been trying to find ways that the cycles of the objects they observed were connected.

Evidence of these studies can be found in monument inscriptions, the Postclassic codices -- and even in their buildings, which they would orient towards various celestial objects. Let's learn more about what's currently understood about ancient Maya astronomy.

Constellations
It looks like the ancient Maya had constellations (and a zodiac), though there's a lot of uncertainty about what they were. One constellation that the ancient Maya may have had was the Pleiades, whose shape may have been viewed as a rattlesnake's rattle. 

Another constellation they may have had was made up of part of Orion. This constellation of theirs was either made of Orion's belt or made of the left-hand star of the belt and Orion's "legs." The three stars may have been seen as three hearthstones connected to creation -- but there may have been another idea among them that the stars were seen as a turtle.

Earth
It doesn't look like the ancient Maya ever figured out that Earth is ball-shaped or that it orbits the sun. Instead, the ancient Maya thought that our planet was the middle of all layers of reality. They thought that it was a crocodile/crocodile-like creature or caiman or a turtle, and they thought that they lived on the back -- another theory says these were just metaphors. (There's also art that shows Earth as a creature with two heads called kawak.)

They thought that they lived above their underworld and below a place that we call the upperworld. (And it's possible they believed the underworld had 9 layers and the upper world had 13 layers.) The upperworld is where the ancient Maya thought the celestial objects that were gods lived.

They thought that the world was made of four parts or quarters. Each of the four had certain things connected to them -- one of these was colors: east was red, west was black, south was yellow and north was white. The center of their world had a color too, but which color depends on the source: examples from sources include blue, green or blue-green.

Eclipses
The ancient Maya knew about lunar and solar eclipses, and sort of knew how to predict them. They used two groups of moon-based months, 148 days (five months) and 177/178 days (six months) as a way of figuring out when eclipses would occur. One artifact that shows they studied eclipses is the Dresden Codex; pages 51 through 58 look like they were for eclipses. (Whether they were lunar or solar is debated). 

Solar eclipses seem to have been an event that the ancient Maya thought was dangerous. Though perhaps they were dangerous if they happened in certain "bad" astrological times. 

Jupiter
An 819-day count may have been used by the Maya in the Classic Period to track Jupiter. The tun (a period of 360 days) and the katun (20 tuns or 7,200 days) may have been connected to Jupiter. The ancient Maya tracked Jupiter in order to time their wars to happen in connection certain positions of that planet. (This count is thought to have been used with Saturn as well, perhaps along with other cycles.) 

A god that archaeologists call K'awiil or god K might be connected to Jupiter. This god is also connected to the sky, lightning, snakes, and storms as well as ancestors and rulers. 


Mars
The ancient Maya had a cycle of 780 days that tracked Mars. And it seems they thought there was a supernatural creature that was linked with the planet. Archaeologists call this creature the Mars Beast. (The creature might be linked with the rainy season too.)

Mercury
The Maya tracked Mercury, using the number 117. (Mercury's orbit is more precisely 115.8 days). You can see evidence for this in the Dresden Codex. 

The Milky Way
The Milky Way may have been thought to be a path/road that the spirits of the dead traveled on. Another idea among them was that it was a river -- another idea it seems they had was that it was a river with a crocodile-like creature in it. The ancient Maya also associated the Milky Way with three things: rain, wind and lightning.

Moon
The ancient Maya followed the moon's path, but it doesn't so far seem that they had an official, separate moon calendar. What they did have was what we call today the "lunar series," which was part of inscriptions. The lunar series describes information about the moon on a particular date, including how far along in the month it was. Moon months to the Maya could be 29 days or 30 days, depending on the month.

The moon itself was connected with eclipses. There was an idea among the ancient Maya, among other ideas they had, that eclipses were fights between the sun and the moon. 

As for supernatural connections, the goddess Ix Chel may or may not have been a 'young' moon goddess (as well as a goddess of other things.) But there are those who don't think she was connected to the moon at all -- instead they think there's a different goddess, which can be seen in the Dresden Codex, on page 49a.


Saturn

The ancient Maya followed Saturn's orbit with a cycle of 378 days. They also, as you probably read above, used an 819-day cycle for Saturn (as well as Jupiter), perhaps along with other cycles. It seems that, like Venus, the ancient Maya used certain positions of Saturn and Jupiter to time wars. 

An aspect of the god Pawaaj (or god N) named Pawaaj Sahb'iin could have been the god Saturn. Or he may have been Saturn's messenger. 

Sun
The ancient Maya tracked the sun's path across the sky (called the ecliptic), which in their art they showed as a double-headed snake. They would build their buildings according to the various points of the sun's path, such as the equinoxes. 

One example is this: in the Preclassic Period, it was popular to orient your structure to both the solstices' sunsets and the solstices' sunrises. There was even a type of building group they would construct as a kind of sundial -- these are called E groups by archaeologists.

To the ancient Maya, the sun was also a god. They thought he had different aspects -- one was the 'jaguar sun,' which he became at night and went through the underworld. This god was also connected to kings. Names archaeologists use for the Maya sun god is K'inich Ahaw and god G.

Venus 
This brightest planet in the solar system was to the ancient Maya a very important "star." One name for Venus that the ancient Maya used for the planet was Chak Ek' or Great Star.  From what has been found, Venus was a celestial object that represented violence. How?

It seems rulers used parts of its orbit to figure out times for wars to get captives to kill as sacrifices. (However, nowadays, it looks like the ancient Maya more often used Jupiter and Saturn to time their wars more often than Venus.)

But there are also many theories about Venus's aspects and functions.  One theory says that there was a belief among the ancient Maya that it made eclipses happen.

Consideration: 63 Day Cycle
Unless further evidence shows otherwise, in the Classic Period at least, there was a 63-day cycle that was used to sync different celestial objects' cycles.  In the examples found, the 63-day cycle looks like it was for fire rituals for the god Pawaaj Sahb'iin.
