It is true that the Babylonians had a day called shabattum or shapattum. This seems, however, to be distinct from the days of restriction dealt with in the calendar tablet. In a syllabary shapattum is equated to urn nule libbi, that is, "day of the rest of the heart." It has been urged that here is a proof that the Babylonians had a Sabbath which, like that of the Hebrews, was a rest day. But it is clear from the Babylonian penitential psalms that the real meaning of the words is "day when the heart (of the gods) is propitiated." A tablet discovered by Pinches shows that the shapattum was the 15th day of the month. A passage in the astronomical poem of the Babylonian epic Enuma elish quite clearly shows that the shapattum is the day of the full moon. The verb shapatu is elsewhere explained as equivalent to the verb gainaru, meaning "to be complete, full." None of the attempted etymologies for Sabbath from the Hebrew is successful, probably for the reason that the word is older than the Hebrew language. It is not unreasonable to suppose that both shapattum and sab bath are descended from a word belonging to the older tongue from which both the Babylonian language and the Hebrew de veloped, and that its prime meaning is "full moon day." This would confirm Meinhold's theory that among the Hebrews the Sabbath was originally the full moon day. But the fact that the name is derived from a common source, and that the day itself among both peoples is originally the day of the full moon, must not blind us to the truth that the Babylonians had no real equiva lent to the Jewish Sabbath at regular seven-day intervals. Had
there been any great likeness between the ways in which the sha pattum and the Sabbath were celebrated the latter could hardly have been insisted on as a distinctive mark of the Jews.
The term has been adopted in universities for a period of free dom from academic duties every seventh year.
