History Tidbit: The Language of the Law

While reading at Matthew Ferguson's blog I came across the following thought-provoking detail quoted from W.E.H. Cockle.  In State Archives in Graeco-Roman Egypt from 30 BC to the Reign of Septimius Severus, Cockle says

“In legal contracts or documents the language of the contract determined the law which would apply. In case of disagreement a Greek contract was judged by Greek law, an Egyptian Demotic contract by Egyptian native law, and a Latin contract by Roman law.”

 I must now see if I can get JPASS register and read to work for me so I can read Cockle's whole article.  I dearly miss having university access to JSTOR.
