We have divided the work into sections for analytical purposes, and in order to aid in the work of indexing and giving cross references. We have arranged the sections in what we believe to be the best chronological order, but have not attempted to justify our chronology, because space would not permit. We have also given the time and place of each section, where these things could be ascertained with any degree of accuracy. In this matter, however, we are liable to disappoint many of our readers, because we have been conservative. The dates and places given in similar works are too often more arbitrary assumptions: there being so little ground of reason back of them that they do not even justify one in calling them speculative. Unless we have had some reason for fixing a date or assigning a locality, we have refrained from doing either, though we have found them freely and positively asserted in such places in similar works.
