Pegasus capital from the Temple of Mars Ultor

The pilaster capital shows some rather capricious ornament: resting on a wreath of acanthus leaves is Pegasus, the winged horse, whose abdomen merges with the vegetal decoration and volutes. Only the left side shows detailed rendering, the design on the right has merely been faintly laid out. While the horse is fully integrated into the architectural form on the left, it appears to dash forth more strikingly on the right. What makes this work unusual is that it would appear that each half was modelled on a different design from the stock of workshop materials available.
