This is a joined chest that would have been made in the Connecticut River Valley near Hadley Massachusetts from 1680 to 1730. It origins go back much further, it’s medieval really, The designs decorating this chest are said to derive from pagan fertility symbols.
They were made for young women as hope chests, as this one was. It is made of red oak, sassafras and aromatic cedar.
The carving on these chests is of highly stylized, and abstracted, leaves flowers and vines, using a flat chip carved technique. You can see in the first picture how the pattern is repeated and flipped again and again. It was fun to do. It makes me think of Celtic stone carving. On top of the chest is a bible box made of sassafras carved with a similar tulip-vine pattern. A raking light really shows it off.
