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 eruption activity and the possible generation of tsunamis. Man-made structures not buried during Minoan A were completely destroyed. The third phase was also characterized by the initiation of caldera collapse. The fourth, and last, major phase (BO/Minoan D) was marked by varied activity: lithic-rich base surge deposits, lahars, debris flows, and co-ignimbrite ash-fall deposits. This phase was characterized by the completion of caldera collapse, which produced megatsunamis. Although the fracturing process is not yet known, the altitudinal statistical analysis indicates that the caldera had formed just before the eruption. The area of the island was smaller, and the southern and eastern
