Attested: Sandonio (or Saudonio) at position 85 in the Ravenna Cosmography
Where: The Roman legionary works depot and possible fort near Holt at SJ406546, beside the river Dee, upstream of the big fortress at Chester. Listed by the Cosmography between Mediolano (Whitchurch) and Deva victris (Chester).
Name origin: Latin sandix from σανδυξ (Pb3O4) and sandaracha from σανδαρακη (AsS) were red pigments. Although sometimes translated as vermilion (HgS), which is brilliantly red, these materials tended to yield paler colours in practical use, and the resin known as sandarac is downright yellow. Therefore it reasonable to guess that sand- here refers to the characteristically red/orange colour of the tiles and pottery produced by the kilns serving the legion.
Notes: Rivet & Smith guessed that this site was Bovium, but that name belongs a few miles away at Tilston. No viable Celtic etymology has been suggested. Although lead was mined a little to the west in Wales, and the ancients were fascinated with heavy metal poisons, the redness of fired clay, even in highly valued Samian ware, is largely due to iron.
