The oldest of them, which has any value, is an account of a Spanish embassy to Tamerlane, the great Tartar potentate and conqueror. Its origin is curious. Henry the Third of Castile, whose affairs, partly in consequence of his marriage with Catherine, daughter of Shakspeare’s “time-honored Lancaster,” were in a more fortunate and quiet condition than those of his immediate predecessors, seems to have been smitten in his prosperity with a desire to extend his fame to the remotest countries of the earth; and for this purpose, we are told, sought to establish friendly relations with the Greek Emperor at Constantinople, with the Sultan of Babylon, with Tamerlane or Timour Bec the Tartar, and even with the fabulous Prester John of that shadowy India which was then the subject of so much speculation. What was the result of all this widely spread diplomacy, so extraordinary at the end of the fourteenth century, we do not know, except that the first ambassadors sent to Tamerlane and Bajazet chanced actually to be present at the great and decisive battle between those two preponderating powers of the East, and that Tamerlane sent a splendid embassy in return, with some of the spoils of his victory, among which were two fair captives, who figure in the Spanish poetry of the time.[323] King Henry was not ungrateful for such a tribute of respect, and, to acknowledge it, despatched to Tamerlane three persons of his court, one of whom, Ruy Gonzalez de Clavijo, has left us a minute account of the whole embassy, its adventures and its results. This account was first published by Argote de Molina, the careful antiquary of the time of Philip the Second,[324] and was then called, probably in order to give it a more winning title, “The Life of the Great Tamerlane,”--_Vida del Gran Tamurlan_,--though it is, in fact, a diary of the voyagings and residences of the ambassadors of Henry the Third, beginning in May, 1403, when they embarked at Puerto Santa María, near Cadiz, and ending in March, 1406, when they landed there on their return.

[324] The edition of Argote de Molina was published in 1582; and there is only one other, the very good one printed at Madrid, 1782, 4to.
