John the Baptist dramatically preaches by the water’s edge to his audience that consists of common people as well as religious leaders. He appears to be in the middle of his harsh pronouncement on the Pharisees and Sadducees, calling them a “brood of vipers.” They stand at the right-hand side of the painting, arms folded, seemingly indignant at John’s words. The rest of the crowd watches and listens intently to John, curious and enthralled by the scene before them. In the distance there are some figures approaching the group. Could it be Jesus on the way to his baptism?
