In general, it was up to the engraver in this period to fit in the
legend around the
type as best he could. He was not instructed in advance how the
legend was to be divided. It is not uninteresting to observe odd breaks when they occur, but the breaks will generally be irrelevant to the definition of
types and the reconstruction of the chronology of the coinage.
That changes in the later empire, when the breaks were often standardized and a change may indicate the beginning of a new issue.
