Completed in 1982, Hart’s depiction of the birth of mankind is considered one of the most important commissions of religious sculpture in the 20th century. The tympanum above the central door features half-formed figures of men and women emerging from the void. Beneath stands the figure of Adam, his eyes not yet open and his body not fully freed from the surrounding stone. The north tympanum depicts the Creation of Day, and the south tympanum depicts the Creation of Night.
