... I think it extremely probable, also, that Shakespeare got his name Claribel from Spenser, whose "Faërie Queene" had appeared some twenty years before "The Tempest" was written, although of course we are to consider always that the name may have been found to Shakespeare's hand in his source-play or novel; for the name Clarabella was probably a thousand years old when Shakespeare was born... Spenser's story will always impress deeply the heart of poets, as does the somewhat similar poem of Keats about the murdered lover and the pot of basil, or Dante's tale of Paolo and Francesca, or Shakespeare's Othello.
