Houses had thatched roofs, thick straw piled high, with no wood underneath. It was the only place for animals to get warm, so all the cats and other small animals (mice, bugs) lived in the roof. When it rained it became slippery and sometimes the animals would slip and fall off the roof. Hence the saying "It's raining cats and dogs."
There was nothing to stop things from falling into the house. This posed a real problem in the bedroom, where bugs and other droppings could mess up your nice clean bed. Hence, a bed with big posts and a sheet hung over the top afforded some protection. That's how canopy beds came into existence. The floor was dirt.. Only the wealthy had something other than dirt. Hence the saying, "dirt poor."
The wealthy had slate floors that would get slippery in the winter when wet, so they spread thresh (straw) on floor to help keep their footing. As the winter wore on they added more thresh until, when you opened the door, it would all start slipping outside. A piece of wood was placed in the entrance-way. Hence: a thresh hold.
In those old days, they cooked in the kitchen with a big kettle that always hung over the fire. Every day they lit the fire and added things to the pot. They ate mostly vegetables and did not get much meat. They would eat the stew for dinner, leaving leftovers in the pot to get cold overnight, then start over the next day. Sometimes stew had food in it that had been there for quite a while. Hence the rhyme: ''Peas porridge hot, peas porridge cold, peas porridge in the pot, nine days old''.
Sometimes they could obtain pork, which made them feel quite special. When visitors came over they would hang up their bacon, to show off. It was a sign of wealth that a man could, "Bring home the bacon." They would cut off a little to share with guests and would all sit around talking and ''chew the fat''.
Those with money had plates made of pewter. Food with high acid content caused some of the lead to leach onto the food, causing lead poisoning and death. This happened most often with tomatoes, so for the next 400 years or so, tomatoes were considered poisonous.
My comment: Were tomatoes common in England 500 years ago? I doubt it.
Bread was divided according to status. Workers got the burnt bottom of the loaf, the family got the middle, and guests got the top, or ''The Upper Crust''.
Lead cups were used to drink ale or whisky. The combination would sometimes knock the imbibers out for a couple of days. Someone walking along the road would take them for dead and prepare them for burial. They were laid out on the kitchen table for a couple of days and the family would gather around and eat and drink and wait and see if they would wake up. Hence the custom of ''Holding a Wake''.
