The undulating frieze allows for plenty of leg room as do the gigantic Y stretchers and ornate central column.
The table is believed to have come from a vineyard / chateau, evidenced by the "angels' share" staining (or tannins / red wine?) on the understructure.

Impressive large French Louis XV revival oak dining table dating from about 1870
Made from solid oak with acanthus leaf hand-carving on the frieze and cabriole legs. This is a rare table as it was made as one piece 400 cm long and 138 cm wide, not with an extendable top which was the standard practice.
The prominent oak medullary rays give the table a beautiful grain pattern brought out by the wax re-finishing; fully restored, solid structure.
