Zeus
According to ancient Greek mythology, Zeus led the gods of Mount Olympus in a battle with a bunch of earlier gods called Titans. The Titans were defeated and fell into the underworld where they were banished. Above, The Fall of the Titans by Cornelis van Haarlem c.1588 depicts the Titans falling, and interestingly, they're all naked males.
Zeus then became the king of the gods. He was also the god of thunder. The bronze statue above, c. 460 BC, depicts either Zeus wielding a thunderbolt or the god Poseidon wielding a trident – nobody is sure which.
This statuette from the 5th century BC shows Zeus wielding a thunderbolt. Note that this ancient Greek representation of a thunderbolt is spindle-shaped, not a jagged line like a bolt of lightning.
A Roman statue of Jupiter with a thunderbolt, 2nd-3rd century AD. The Romans identified their god Jupiter with the Greek god Zeus.
A statue of Jupiter c. 150 AD, in the Louvre, Paris, holding a thunderbolt in his right hand. His upraised left hand probably held a scepter, now broken off, to show his kingship. Zeus/Jupiter was also identified with the eagle. Any time you see a Greek or Roman statue with an eagle, it's Zeus or Jupiter.
Jupiter Tonans (Jupiter the Thunderer), 1st century AD, in the National Museum in Warsaw. The thing that looks like a sponge in his right hand is probably a thunderbolt.
Zeus, a Roman (175-200 AD) copy of a Greek original (350-300 BC). Again, his right hand holds a thunderbolt, and the thing in his left hand that looks like an ice cream cone is probably part of a royal scepter.
A Roman statue of Jupiter/Zeus copied from a Greek original, in the Musei Capitolini in Rome. The eagle shows that it's Zeus, and what looks like a bar of soap in his right hand might be part of a thunderbolt.
There are many, many myths involving Zeus. Previously, we looked at the myth of Zeus and Ganymede, shown on this Greek dish from 460 BC. Ganymede, at right, was a beautiful mortal youth whom Zeus brought to Mount Olympus to serve forever as his cupbearer and his toy boy. Yes, Zeus was bisexual.
We end with this modern painting of Zeus with an organ in a state not seen in the ancient artworks but implied by all the stories of Zeus fathering children by a bevy of women as well as being Ganymede's sugar daddy.
To quote the ancient Greek playwright Aristophanes: "Open your mouth and shut your eyes and see what Zeus will send you."
