This painting of Jupiter from first century Pompeii is tailor made for the Emperor card. Although this work predates the Tarot by some thirteen centuries, all the elements of the Emperor are present.

We see Jupiter, seated upon his throne, as a winged Victory sets a laurel upon his brow. He holds a scepter in his hand, and an orb and an eagle are at his feet. The image succinctly and elegantly telegraphs command, majesty, and authority.
