Greeks embedded the arrival of winemaking culture in the mythologies of Dionysus and the cultural hero Aristaeus. Early remnants of amphoras show that the Mycenaeans actively traded wine throughout the ancient world in places such as Cyprus, Egypt, Palestine, Sicily and southern Italy. As the Greek city-states established colonies throughout the Mediterranean, the settlers brought grapevines with them and were active in cultivating the wild vines they encountered.

Leyden jar used in demonstrations. The jar is constructed out of a glass cup nested between two fairly snugly fitting metal cups. When the jar is charged with a high voltage and carefully dismantled, it is discovered that all the parts may be freely handled without discharging the jar. If the pieces are re-assembled, a large spark may still be obtained from it. This demonstration appears to suggest that capacitors store their charge inside their dielectric. This theory was taught throughout the 1800s. However, this phenomenon is a special effect caused by the high voltage on the Leyden jar. In the dissectible
