But, according to Strabo, the Romans found out the trade at last. Publius Crassus (whoever he may have been) sailed across to the islands, ascertained that tin was near the surface, and indicated the route for the benefit of traders, “although the passage was longer than that to Britain.”
If we do not admit the identity of Scilly with the Cassiterides, we have no proof that the Romans had dealings with the islands before their occupation of Britain.
CRAB-POT-MAKING BY ST. AGNES CHURCH
The origin of the name “Scilly” is wrapped about with mystery. Not that there is any lack of suggestions; on the contrary, there is such a plethora of them that one feels no “forrader” after having heard them all.
One learned writer says with confidence, “The islands take their name from the old Silurian inhabitants to whom they served as a last refuge.” Other ideas are that the name is derived from “Sulleh,” a British word meaning “rocks consecrated to the sun,” or from a Cornish word signifying “divided.”
The inhabitants themselves seem to favour most the notion that the conger-eels, locally called “selli,” have given their name to the islands.
There are other suggestions; but as to which of the many is the most probable we must leave antiquarians and topographers to fight it out between them, and when they are all agreed we may conclude we have arrived at a certainty of the truth; and that is, perhaps, only another way of saying that we shall never know!

The most common Cornish words found in the place-names of Scilly are:—
