Regarding the identity of the man with the cane

A careful observation of this column statue reveals an asymmetry in the character's feet. A figure from the Old Testament could correspond to this iconographic detail: it is Jacob.

Jacob is the patriarch most frequently mentioned in the New Testament, either alone or with Abraham and Isaac.
In the Book of Genesis, he wrestles with an angel. Although he emerges victorious from this struggle, he is injured in the hip and is sometimes considered lame as a result of this episode.
