I’ve always wondered how the ancients came to standardize their measures (like weights). That the stone frog shown here was (AFACBD) considered a “weight” is one thing: but one has to think about what it was considered a “standard” against. Was it carved (and this object is obviously carefully crafted) to correspond to a set value of “weight”? Or were weights - important in Mesopotamian antiquity, since weight of stuff (mainly grain ) seems to have been the basis of their “economy” -more-or-less arbitrarily determined?
