A Hohokam petroglyph can be found in the Saguaro National Monument, AZ. and it is believed that the carved spiral represents the water symbol.
What’s the true connection between this carving and the Hokoham culture which occupied the region of present-day Tucson and Phoenix, AZ.?
The spiral, a magical symbol, was once carved on the rocks of Sahara, in the times when this region of the world was an immense green garden and it was very long time ago and the breast of Astarte, the ancient Phoenician great goddess of fertility, motherhood, and war (the counterpart of the Babylonian goddess Ishtar) is depicted with spirals.
The spiral is also discovered on the elaborate vestments of the Orochi (Oroki), a small indigenous nation of the Far East (Island of Sakhalin and the mouth of Amur river). However, the spiral motif that dominates a wide variety of cultures has different meanings.
The spiral motif on the ritual chalices of Hazor, the Canaanite center of northern Palestine, famous in the nineteenth century BC – had a different meaning than a prominent, spiral pattern on the Danish shields and ornaments dated 3000 BC.
