have uniformly the incuse square on the reverse. These may be placed after 500 B.C. “Notwithstanding their archaic appearance, it does not seem that these little coins are much earlier than the middle of the 5th century.”
II. Next comes a series, chiefly obols for the most part with head of Apollo on obverse, and a wheel on reverse, the latter probably a development of the earlier incuse square. They are mostly obols of 13-8 grains.
III. About the middle of the 4th century the drachm first appears with the head of Artemis on obverse and a lion on the reverse, weighing 58-55 grains.
Now over all Gaul, and far into Northern Italy, and the valleys of the Alps, as far as the Tyrol, the coinage of Massilia made its way and was abundantly imitated. In fact these imitations formed the entire medium of those regions until the Roman conquest. The imitations of the little coins with Apollo and the wheel as reverse are found right into the north of France, and in England.
