Helios vs Tonatiuh

The Titan-born sun who drives his chariot across the sky each day and sees everything beneath it. Son of Hyperion and Theia, brother of Selene (Moon) and Eos (Dawn), Helios is the witness gods and mortals call on because nothing happens outside his gaze.

Helios was born to the Titans Hyperion and Theia, together with his sisters Selene and Eos. Hesiod lists the three light-bringers as a single brood; the Homeric Hymn to Helios names their mother Euryphaessa, 'far-shining', a title that may be another name for Theia.

Hesiod names Helios as a child of the Titans Hyperion and Theia, born with his sisters Selene and Eos. He is not an Olympian but an older power, and Greek poetry treats him less as a ruler than as a witness: because he crosses the whole sky every day, he sees what others miss.

The sun god of the Fifth Sun (the current world age). Tonatiuh demanded human hearts and blood to fuel his daily journey across the sky, driving the Aztec system of ritual sacrifice.

After the destruction of the Fourth Sun, the gods gathered at Teotihuacan. Nanahuatzin threw himself into the sacrificial fire and rose as the Fifth Sun. The other gods sacrificed their hearts to make him move, establishing the cosmic debt that humans must repay through sacrifice.

Tonatiuh ("He Who Goes Forth Shining") was the **sun of the current world age**, the Fifth Sun. In Aztec cosmology, four previous suns had been destroyed, each ending in cataclysm. Tonatiuh was the current sun, and the Aztecs believed he required **human blood and hearts** to maintain his journey across the sky.
