At the density of pure water, 1 kg per litre, the contents of a full pithos would weigh about a tonne. Moreover, the pithos selected was not among the largest. On similar studies of some other pithoi mentioned by Ventris and Chadwick, he obtained volumes such as 1430.5 liter, 1377.5 liter, 1334.7 liter, and so on, with full weights in excess of two tons. Dry goods would be much less dense, but even half the density, a weight of about a ton, is far beyond any handling operations by individuals, or teams of individuals, who could not obtain a purchase in sufficient numbers in the space around the jar to effect even a simple lift.
