In the Vindolanda Tablets [
http://vindolanda.csad.ox.ac.uk/ ] there is a shopping list from a woman to her husband or servant who was down south. She asked for something like 500 eggs, just an astonishing number. So it seems eggs were vastly eaten.
Well now we cannot say that eggs have not been held in high regard - they always have been. Lenten abstinance observations have traditionally barred one from eating them as they were considered opulent in times past.
But we cannot infer entire demographic patterns from a sinlge written instance.
The fact that the Roman woman in question was writing anything at all, to a servant or husband at some distance, indicates a person of wealth and standing. She may have had dozens of people in her household to consider when her shopping list was compiled. Maybe the prefect was coming to dinner and she was looking to impress. She was ROMAN, in fact, which tells much. They were known for bringing Rome to the subjugated lands, not the other way round. It's probably due to the Romans that eggs are eaten at all in England!
The enitre episode suggests, at least, that eggs were not a common thing, or she would not have had to send off for them.
In more modern times, I wonder if this hasnt carried into the English diet. I distinctly recall Ian Flemings character, James Bond, eating only one egg for breakfast, as more than that would be overindulgent.
If fiction is a reflection of the culture that creates it, as most literary types suggest, then the 4 Egg Whopper Omelet might not be as prevalent in England as here in the States.
I recall when I was there some years ago that they made the comment - "Oh yes, you're a Yank. I forgot - so sorry. You'll be wanting 2 or 3 eggs then, with your breakfast, right?" The implication was that someone might have to toddle off to the local kiosk and pack in a few extras, just for me. The English are a polite bunch!
Most of what I have read and learned about England as a whole puts eggs lower in the scheme of comestibles. Thats why I said what I said. I may be off base, too.
