his year marks seventh cen? tenary of famous Spanish Code, JL Las Siete Partidas (The Parts), compilation of which was com? pleted in 1265 by King X of Cas? tile. Hence, this would seem to be an opportune occasion to discuss work. To make information on code fur? ther cabalistic, references in historical works state that Seven Parts took 7 years to complete. Unlike most antiques, this work has refused to become useless and gather dust. An extensive body of litera? ture in various languages by authors of many nations attests to worldwide in? fluence of this legal compendium and to fact that it still remains of practical appli? cation not only in its own country but in other civil law jurisdictions as well. As such it has outlived its predecessors and even many of its successors. The present discussion is limited to a brief bibliographical description of fine collection of early editions of Siete Partidas in Law Library collections and to an outline of some historical and evalu? ative information which may serve to sup? port universal claim made with respect to importance and excellence of this work over centuries.

X is often described as a man of vision who distinguished himself not only in law, but also as a historian, grammarian, poet, and mathematician. An American work by Walton, Civil Law in Spain and Spanish America (Washington, 1900), states, Alfonso X was recognized as one of leading wise men of his time, Justinian of Spanish jurisprudence, and he demonstrated his wisdom by giving to pos? terity his work of Siete Partidas, most notable code of that age. 1 It is particularly surprising that a logical, philosophical, and very detailed legal com? pendium of this magnitude could have been planned and perfected in midst of confusion and chaos that obtained in Spain in early 13 th century throughout country's social, political, and religious af? fairs.
