"The Cid Campeador" by Antonio de Trueba is a historical romance novel. The "Cid Campeador" has been for centuries the great popular hero of Spain. He takes the same place in that country as King Arthur does in England, Roland, or Rolando, in France, and William Tell in Switzerland; and, like them, his life and exploits are, to a great extent, founded on popular traditions. In English-speaking countries, there is very little known respecting him, and the translator ventures to place before the public a work which is considered by Spaniards to be one of the best historical romances in their literature. It is founded on a large number of ballads and other poetical pieces, extant in Spain for centuries, and on a very old work named "The Chronicle of the Cid."
