The Koran was not collected or arranged until after Muhammad's death. It is to be regretted that there is no reliable record of the exact order in which its various verses and chapters were given to the world by the Prophet, as that would have given us a great insight into the working of his mind from the time that he began his first recitals up to the time of his death. It is true that attempts have been made to formulate the order of delivery, but these can only be more or less conjecture. At the same time, though earlier and later verses appear mixed up in the different chapters, in some cases, of course, the period to which they belong can be pretty accurately fixed and determined. As an interesting work, it can hardly be compared with our Old and New Testaments, nor would it be fair to make such a comparison. It must be remembered that the Koran is the work of Muhammad alone, while the Biblos, or Book, commonly called the Bible, is the work of many men. In its compilation many authors were rejected, and it represents as a whole the united talents of the ages. Indeed, the Bible may be considered as the most wonderful book in existence, and certainly the most interesting after visiting the countries it describes and the localities it refers to. If read from a matter-of-fact point of view, it gives an abundance of various kinds of literature, and describes the workings of the human mind from the earliest ages, and the progress of ideas as they gradually and slowly dawned upon man and drove him onwards. If read from a spiritual or mystical point of view, it can be interpreted in many ways to meet the views of either the readers or the hearers. In a word, the Bible is full of prose and poetry, fact and imagination, history and fiction. It was lately described in an Italian newspaper, _Il Secolo_, about to issue a popular edition of it in halfpenny numbers, as follows: 'There is one book which gathers up the poetry and the science of humanity, and that book is the Bible; and with this book no other work in any literature can be compared. It is a book that Newton read continually, that Cromwell carried at his saddle, and that Voltaire kept always on his study table. It is a book that believers and unbelievers should alike study, and that ought to be found in every house.' As a scientific work it has little value except that it represents the extent of scientific knowledge possessed by the authors at the time the different books were written.
