A dictionary of Arabic words with their explanations in Latin. At the beginning there are five pages of printed matter containing the preface. The title-page, unfortunately, is missing. The rest of the book is in manuscript, and looks as if it had never been completed in print.The author is Dr. Thomas Erpenius, the Dutch Oriental scholar, who was born 1584 and died 1624 C.E.. His Arabic Grammar, often reprinted, has, almost to the commencement of the nineteenth century C.E. , been one of the good elementary books in the West employed by students. This is probably the holograph copy.
