The reasons for supposing the Cassiterides to be the Scilly Islands are thus stated in Camden’s Britannia: They are opposite to the Artabri in Spain; they bend directly to the north from them; they lie in the same clime with Britain; they look towards Celtiberia; the sea is much broader between them and Spain than between them and Britain; they lie just upon the Iberian sea; there are only ten of them of any note; and they have veins of tin which no other isle has in this tract.—Camd. Brit. p. 1112, ed. 1695.

Siluram quoque insulam ab ora, quam gens Britannia Dumnonii tenent, turbidum fretum distinguit: cujus homines etiamnum custodiunt morem vetustum: nummum refutant: dant res et accipiunt: mutationibus necessaria potius, quam pretiis parant: Deos percolunt: scientiam futurorum pariter viri ac feminæ ostentant.—Solin. Poly. c. 22. Cassiterides insulae spectant adversum Celtiberiæ latus: plumbi fertiles.—Ib. c. 23.
