while the second arch depicts scientists including Albert Einstein, Charles Darwin, and Hippocrates. Other figures depict the months of the year. The columns framing the door jambs beneath the archivolts are decorated with capitals and gargoyles at the top and bottom, and a single figure in the middle. In the tympanum above the doors and below the archivolts is a figure of Christ seated, which is flanked by the symbols of the Evangelists. When Riverside Church was completed, there was controversy over the inclusion of Einstein, a living Jewish man, because the other figures represented people who had since died. According to the publication Church Monthly, during construction, the committee tasked with the church's iconography had proposed depicting 20 scientists, not including Einstein, on the facade. The faculty, however, unanimously decided Einstein should be included because he was indisputably one of 14 "leading scientists of all time". The chapel entrance on Riverside Drive south of the main entrance contains two archivolts that are supported by two sets of columns. The archivolts depict symbols of the zodiac and the second archivolt contains an elaborate decorative molding. A tympanum relief below the archivolts depicts the Virgin Mary flanked by two angels who are mirror images of each other. Sculpted elements are also placed within niches that are spread across the church's facade. Above the main entrance on the western facade are sculptures of seven kings. Statues are also included in the tower's niches, as well as in niches on the facade of the cloister entrance to the east. The facade also has gargoyles, which are outside the carillon near the top of the tower. The northern section of the nave's roof contains Angel of the Resurrection, a bronze statue of a trumpeter atop a pedestal. Interior elements The carvings inside the church correspond to the respective uses of the areas in which they are sited. For instance, the 20 quatrefoil medallions inscribed on the chancel railing depict the typical "interests, emphases, activities, rites, and ceremonies" that are conducted within the chancel. Around the pulpit are sculptures of ten Old Testament prophets. Above the nave, the southern wall of the upper seating gallery contains multi-tiered niches, whose upper tiers contain sculpted figures of ministers. The two central niches contain a cast of Epstein's gilded-plaster sculpture Christ in Majesty. There seven-paneled chancel screen at the back of the chancel is carved from Caen stone.
