The Ancient Maya of El Mirador built triadic structures that represented the three hearthstones, held sacred by the Maya.
The fire in the middle represents the place of creation. These three hearthstones -in turn- are also represented by 3 stars you will find in "our" constellation of Orion, while the fire is Orion's nebula, M42. The Maya assigned great importance to transmitting their creation mythology through their architecture. So important it was that the Maya astronomer could "see" the three hearthstones in the night sky just below the Turtle Constellation.
