superior in versification to the Tesoro, that it is doubted whether they can be the production of the same man and age. The most useful work that owed its existence to his superintendence was the Alphonsine Tables, containing calculations truly extraordinary for that period. Alphonso XI. followed in his footsteps in the cultivation of the Castillian language. He is said to have composed a General Chronicle of Redondillas, which is lost. It was in the time of Alphonso XI. that Don Juan Manuel wrote his Count Lucanor, a series of tales put together somewhat in the style of the "Seven Wise Masters." An inexperienced prince, when in any difficulty, applies to his minister for advice, who replies by relating some tale or fable, concluded by a maxim in verse, as the moral of the story. These show his knowledge of the world; and one, in opposition to that of the Grecian sage, who said, men were to treat their friends as if they were one day to become their enemies, deserves to be recorded in honour of the more noble-minded Castilian; "Quien te conseja encobrir de tus amigos, engañarte quiera assaz, y sin testigos." "Whoever counsels you to be reserved with your friends, wishes to betray you without witnesses." Count Lucanor is praised for the artless simplicity of its style, joined to acuteness of observation. In addition, Manuel composed a Chronicle of Spain, and other prose works, as well as several poems. The civil wars and rebellions that desolated Spain at this time checked the literary spirit, and prevented the cultivation of learning. Juan Ruiz, arch-priest of Hita, and Ayala, the historiographer, are almost the only names we find in addition to those already mentioned. Juan Ruiz wrote an allegorical satire in Castillian Alexandrines.
