The peculiar piece of late Byzantine legal literature which is known by the strange name of Tipoukeitos, is concerned with the so-called Basilica. It indicates, in a very succinct form, the topics dealt with in the sixty books of Emperor Leo the Philosopher's voluminous codification. It seems that the author of T. used a copy of B. which differed somewhat, particularly in its enumeration of the single texts, from those MSS on which the brothers Heimbach based their edition of B. but, in general, the order of books and titles in T. is the same as in the Heimbachs' edition.
