 Together with the Sarcophagus of Junius Bassus, it one of the most important examples of Christian-Roman sculpture of the Constantinian era.It draws its name from its clear references to the dogmas of the Council of Nicaea (325), in particular to Christ being consubstantial with God the Father, as shown (for example) by the scene of a figure with the appearance of Jesus between Adam and Eve, though whether the figure is to be understood as Christ or God the Father is less clear – the dogmatic point works either way.The front face is split into two registers, typical of the style of the time, with Old Testament and New Testament subjects and a central shell-shaped "clipeus" containing the portraits of the dead couple, embraced and wearing marital clothes typical of the 4th century ("tunica manicata", "dalmatina" and "toga contabulata" by the man, who holds a "rotulus" in his hand, and tunic and palla by the woman).
