the pall reversed (that is, upside-down y-shape) symbolizes the forks of the rivers main and aschaff, which, in a way, also makes the arms canting, as the community’s name is drawn from a fusion of these two rivers’ names. the stripes on the dexter (armsbearer’s right, viewer’s left) side come from the arms formerly borne by the counts of rieneck, to whom parts of the community historically belonged. the halved wheel comes from the electorate of mainz’s coat of arms, the community having belonged to this state until 1803. the tinctures azure (blue) in the escutcheon’s base and argent (silver) in the pall reversed are bavaria’s colours, which have flown over mainaschaff since 1816.
