Is Ius Equal to Lex? or: What is ius civile? A Greco-Roman approximation in the Institutes of Justinian

This article deals with one of the unidentified fragments of the Institutes of the Justinian law compilation (Inst. 1.2.2a). It is argued that the specific passage as well as the arrangement of the whole title on ius naturale, ius gentium and ius ciuile reveals the individuality of Justinian's compilers, and therefore of their legislative and educational program, as well as of their didactical approach, particularly towards Greek-speaking students while redacting the Corpus Iuris Civilis.
