By the mid-17th century, the Catholic Church formally banned the depiction of the Trinity as a three-faced (or three-headed) figure, judging it theologically problematic and pastorally misleading.
In 1628, Pope Urban VIII, through the Congregation of the Index, officially condemned such representations. Artists were instructed to use approved Trinity iconography: typically, the Father as an elderly man, the Son as Christ, and the Spirit as a dove—distinct, yet unified by light or gesture.
Another option (less recommended but tolerated) was to represent the Holy Trinity as three angels, since it's a image present in the Old Testament.
