Impost (architecture)

[1][2] The imposts are left smooth or profiled, and "then express a certain separation between abutment and arch.

In the Gothic period, the fighter almost completely disappeared from the calyx bud capital.

The architecture of the Renaissance returns to the formation of the imposts of the ancient column orders.

[4] Sometimes, the complete entablature of a smaller order is employed, as in the case of the Venetian or Palladian window, where the central opening has an arch resting on the entablature of the pilasters which flank the smaller window on each side.

In Romanesque and Gothic work, the capitals with their abaci take the place of the impost mouldings.
