undertook to edit a series of Old Norse texts, among which was the _King’s Mirror_, which was published under the auspices of the University of Christiania in 1848. The Christiania edition is based on the main manuscript of the _Speculum Regale_, the manuscript 243 B of the Arnamagnean collection. This was produced in Norway some time during the last quarter of the thirteenth century, perhaps not long after 1275.[157] As the manuscript was incomplete in part, the editors also made use of the copies which had been made the basis of the earlier edition. Inasmuch as the materials to be used had been copied at different times and consequently reflected various stages of linguistic development, it was thought desirable to normalize the orthography: and in this part of their task the editors made use of a fragment which was thought to belong to a somewhat earlier date than the main manuscript.[158] If this belief is correct, the Christiania edition must, in respect to orthography, be a comparatively close approximation of the original manuscript.

In 1881 a third edition prepared by the German philologist Otto Brenner was published under the title _Speculum Regale, ein altnorwegischer Dialog_. Brenner based his text on the Norwegian manuscript 243 B, but he also made use of the Icelandic copy (243 A) and of some of the older fragments. His edition consequently includes all the materials that had been used in the earlier editions. It was Brenner’s purpose to prepare a text which should give the Norwegian version in its original form, so far as such a restoration is possible. Though scholars are not agreed that Brenner achieved his purpose, all have acknowledged the value of his work, and since its publication his version has been regarded as the standard edition. Two years ago (1915) the University of Illinois published, under the editorial direction of Professor George T. Flom, a photographic reproduction of this same manuscript, 243 B. This important linguistic monument has thus been made accessible to scholars in its original form. Professor Flom has also prepared the Old Norse text of the manuscript, which makes a part of the publication, and has prefaced the whole with an extended introduction in which he discusses the history of the manuscript, marginal addenda, abbreviations, and other paleographic and linguistic problems.
