Some people use locks and safes to guard their possessions, and others use magic. In this card, there is a circle made of planetary and alchemical signs. Above it is a stone head of Jupiter and within it is a square filled with numbers. The circle represents the wheel of change - the impermanence of physical life. The Roman god Jupiter (king of gods, sky and thunder) watches over to protect and preserve what is good (I'm sure he's hiding a thunderbolt somewhere). The 4 x 4 square is Jupiter's "magic square" (kamea in Hebrew); these squares were an arrangement of numbers (usually integers) in a square grid, where the numbers in each row, and in each column, and the numbers in the forward and backward main diagonals, all add up to the same number. Dating back to Chinese literature in 650 BCE, philosophers thought these squares were magical and used them as talismans (both to attract good luck and ward off bad luck). Around the 15th century, manuscripts began to pop up in Europe that described how these squares (assigned to the seven classical planets) could be used to attract the influence of a planet and its assigned angel (or demon). Jupiter's magic square was used for success, abundance, money, and growth. While some RWS interpretations see the Four of Coins as a card for misers, I personally don't see anything wrong with being a good steward of what you have, including using good judgment when it comes to our "stuff." But sometimes we forget that it's not just our material possessions and finances we need to take care of, but our bodies too.
