Herrera wrote several works, chiefly historical. The most important, that on which his reputation rests, is his _Historia general de las Indias occidentales_. It extends from the year 1492, the time of the discovery of America, to 1554, and is divided into eight decades. Four of them were published in 1601, and the remaining four in 1615, making in all five volumes in folio. The work was subsequently republished in 1730, and has been translated into most of the languages of Europe. The English translator, Stevens, has taken great liberties with his original, in the way of abridgment and omission, but the execution of his work is, on the whole, superior to that of most of the old English versions of the Castilian chroniclers. Herrera’s vast subject embraces the whole colonial empire of Spain in the New World. The work is thrown into the form of annals, and the multifarious occurrences in the distant regions of which he treats are all marshalled with exclusive reference to their chronology, and made to move together _pari passu_. By means of this tasteless arrangement the thread of interest is perpetually snapped, the reader is hurried from one scene to another, without the opportunity of completing his survey of any. His patience is exhausted and his mind perplexed with partial and scattered glimpses, instead of gathering new light as he advances from the skilful development of a continuous and well-digested narrative. This is the great defect of a plan founded on a slavish adherence to chronology. The defect becomes more serious when the work, as in the present instance, is of vast compass and embraces a great variety of details having little relation to each other. In such a work we feel the superiority of a plan like that which Robertson has pursued in his “History of America,” where every subject is allowed to occupy its own independent place, proportioned to its importance, and thus to make a distinct and individual impression on the reader.
