Minoan civilization is seen in Minoan handicrafts on the Greek mainland. The shaft graves of Mycenae had several Cretan imports (such as a bull's-head rhyton), which suggests a prominent role for Minoan symbolism. Connections between Egypt and Crete are prominent; Minoan ceramics are found in Egyptian cities, and the Minoans imported items (particularly papyrus) and architectural and artistic ideas from Egypt. Egyptian hieroglyphs might even have been models for Minoan pictographic writing, from which the Linear A and Linear B writing systems developed. Archaeologist Hermann Bengtson has also found a Minoan influence in Canaanite artifacts. Minoan palace sites were occupied by the
Minoan civilization among the most well-supported examples known. Because their language has yet to be deciphered, it is unknown what kind of government was practiced by the Minoans, though the palaces and throne rooms indicate a form of hierarchy. A fresco of saffron-gatherers at Santorini is well-known. The Minoan trade in saffron, the stigma of a naturally-mutated crocus which originated in the Aegean basin, has left few material remains. According to Evans, the saffron (a sizable Minoan industry) was used for dye. Other archaeologists emphasize durable trade items: ceramics, copper, tin, gold and silver. The saffron may have had a religious significance.
