The tendency toward equalization of the two verticals in such characters as [Image/symbol: curved vertical with flat bottom] *pa* and [Image/symbol: curved letter with left loop] *sa*, which begins to make its appearance in some inscriptions of this period, also prefigures developments of later centuries wherein the letters tend to be remodeled into a square frame. This again is an influential development for the history of the derivative scripts, many of which (notably Devanāgarī) retain this pattern throughout their history.
