These four pieces constitute one work which is available in 2 sizes. The Four refers to the number four and it's many instances in our lives as in the seasons, the cardinal directions, the states of matter and the four elements of antiquity. As such four can be seen as one of a series of sacred numbers that define the world in which we live. It is the number of order and regularity in the material world, of truth and honesty, of solidity and reliability.
In the show from which this edition came the works were hung on four sides of the space and in addition symbolized the four Archangels and the four cardinal directions that served to anchor and protect the space.
