Known. A Roman mosaic shows a flower with eight petals.
The villa is on farmland in Devon, England, between Halberton and Sampford Peverell. The floor dates to the fourth century AD. It covers 12 square metres and is made of thousands of red, white, and dark blue-grey tiles. It is thought to have floored a dining or reception room. The flower sits in a round centre, with squares and a knotted line around it. The dig also found a bathhouse with at least two plunge pools of waterproof concrete, a blue glass gem of the goddess Victory, a copper-alloy bangle on the mosaic, and a silver-plated spoon.
A timber stair only hints at a second storey. The page does not prove there was one.
