Cassiterides

Cassiterides, or Tin Islands, were once supposed to be N.W. of Spain, and so marked in Ptolemy's map, then generally considered to be the Scilly Islands or Cornwall, and now again thought by some to be some islands in Vigo Bay off the Spanish coast. Wherever the islands were, the Phoenicians traded with them for tin, but the likeness of the Greek word for tin to a Sanscrit word has led some to think that the Phoenicians brought both metal and name from India.
