The answer is: the sharply foreshortened St. Mark, who descends from above. The Miracle of the Slave (also known as The Miracle of St. Mark, 1548) is a painting by the Italian Renaissance artist Jacopo Tintoretto. Currently housed in the Gallerie dell'Accademia in Venice, northern Italy, it was originally commissioned for the Scuola Grande di San Marco, a confraternity in the city.
