The lion holds a rabbit or dog-like beast in its claws. The burden of the base of a column on its back is shared by a kneeling atlante on its right flank. The corresponding space on the other side is filled by a wedge-shaped block, roughly hewn along a vertical section where the work was separated from its point of anchor.
The combination of lion and atlante, a compressed version of the tiered arrangement of the same motifs found in the supports flanking the major entrances of the cathedrals of Trani and Ferrara, is seen again in Giovanni da Campione's north portal at S. Maria Maggiore in Bergamo. The characterization of the lion, periwigged in a loosely undulating mane, is echoed in the somewhat grosser animals in The Cloisters, New York (No. 126.96.36.199) as well as more distantly in a number of examples around Parma and Verona.
The nose, mane, forelegs, and rear of the lion are considerably worn. The nose of the figure is lost and areas along the column base are chipped.
