These two marble heads both depict Saint John the Baptist and are the remains of two full-length marble sculptures, one created by Tino di Camaino between 1320 and 1324 and the other by a Florentine artist in the first half of the 14th century. Both originally adorned the exterior of the Baptistery. The head sculpted by Tino di Camaino was part of the sculptural group once placed above the South Door, representing the Baptism of Christ. In this composition, Saint John was shown in the act of baptizing the Messiah, who was positioned at the center; the upper portion of this figure is also preserved in this same room. The other head belonged to the group depicting the Preaching of the Baptist, which was placed above the North Door of the Baptistery. A third group, representing the three Theological Virtues—of which only fragmentary remains can be admired in this hall—was positioned above the East Door. The marble sculptures by Tino and his collaborators were removed in the 16th century and replaced by the groups now housed in the Hall of Paradise, created by Rustici, Sansovino, and Danti. Although created by different hands, both heads are distinguished by intense drama combined with a great and noble elegance, characteristics typical of the Sienese master and his workshop.
