This is called the pineapple pattern, for the obvious reasons. It’s one of my favorite patterns, not just because of its graceful curves, but because of the other meanings.
Pineapples have been a symbol of hospitality since the Victorian era. If you look closely, you’ll find them decorating newel posts, carved into doors, and scattered throughout Victorian homes.
There’s a good chance that when this was made, the meaning behind the pineapple had already been lost. It’s amazing all the ideas like that that we hang onto, without understanding why.
