This was the one form of worship that bound all the peoples and races of the vast Empire together, whatever might be their own local gods and religious customs. The government did not much care what other rites and doctrines the people might practice and believe, so long as they showed their loyalty by joining in the imperial cult, and did not engage in secret assemblies where rebellion might be plotted or crime perpetrated.

Finally, through law schools, through the decisions of imperial jurists, and through the legal literature, which reached its height about 200 A.D. in the writings of Ulpian and Papinian, and which is marked by acuteness in reasoning, clearness in statement, and fairness in judgment,
