According to one study, it looks like over the last thousand years or so our artistic representations of the Last Supper have seen the food portions get bigger and bigger:
Has even the Last Supper been supersized?
The food in famous paintings of the meal has grown by biblical proportions over the last millennium, researchers report in a medical journal Tuesday.
Using a computer, they compared the size of the food to the size of the heads in 52 paintings of Jesus Christ and his disciples at their final meal before his death.
If art imitates life, we’re in trouble, the researchers conclude. The size of the main dish grew 69 percent; the size of the plate, 66 percent, and the bread, 23 percent, between the years 1000 and 2000.
Probably doesn’t mean all that much. Still a bit odd and amusing though.
