Granius is cited as an authority in the
Digest of
Justinian, where he is said to have written a book on Papirian law (
Ius Papirianum) as ascribed to the 6th-century BC
pontifex Papirius. A reference in
Cicero to the
Papirii dates the book to sometime after October 46 BC. The
ius Papirianum dealt with the laws of the kings (
leges regiae), which were sacred laws and required knowledge of pontifical records; therefore, the interests of Granius in legal and religious formulas should be seen as compatible. Granius recorded, for instance, that
Numa Pompilius, in founding religious rites for the Romans, struck a deal with the gods to punish those who committed
perjury. It may be that no collection of
leges regiae existed earlier, and the idea that there was a
ius Papirianum originated with the work of Granius at the beginning of
Augustus' reign. He may thus be a more significant jurist than the extremely scant remains of his work would indicate. The point of law cited in the
Digest involves distinguishing a girlfriend (
amica) from a
concubina as defined by law. Granius explained that
pellex (found elsewhere as
paelex), Greek
pallakis, had become the usual term for a woman sleeping regularly with a man who has a legal wife (
uxor), but that formerly it referred to a live-in partner in lieu of a wife. This Granius is sometimes identified with
Granius Licinianus; the latter, however, is almost always dated to the time of
Hadrian. ==References==
