I read this in the latest copy of Good Housekeeping.
Some researchers (who need a life) studied 52 different paintings of the Last Supper that were drawn over the course of a 1,000 years.
They discovered that the main course has increased 69 percent.
The plate size grew 66 percent.
The bread size increased 23 percent.
And since no one really knows what any of it looked like, why are people wasting their time on this?
