About
Olympus turns five minutes of your evening into a ritual: a Greek myth, the real sky above you and the weather, joined together.
THE ORACLE
Each evening Zeus reads your sky. He finds the clearest dark hour in your viewing window from the hourly forecast and names the Myth of the Night: a constellation standing high over your city, or an omen — a storm brings the myth of Zeus's thunderbolt, wind brings Aeolus, rain the weeping Hyades, fog the goddess Nyx, a full moon Selene.
36 MYTHS, RETOLD
30 classical constellations and 6 sky omens, each told in short illustrated chapters, brief or full. Perseus and Medusa, Orion and Artemis, Callisto the Great Bear, Orpheus and his lyre, the Milky Way. Figures pages link the gods and heroes across stories. All myths are in the app and readable offline.
TRIALS
Three questions after each myth. A missed question comes back in a later Trial until you remember it.
WITNESS
Face this direction, look this high, find this bright star. When it is dark and the constellation is up, tap "I saw it" and its bronze medallion turns gold in your Codex.
