To make into marble or to cover with marble; to give a marble-like appearance to something.
From the prefix em- (to cause to be) plus marble (the stone), similar to how 'embark' combines em- + bark to mean 'to put on a bark (ship)'.
This verb is so rare it's almost mythical—a single gem of architectural language used to describe the transformation of ordinary materials into stone-like permanence, capturing the grandeur of classical building.
