In
iconography, the evangelists often appear in
Evangelist portraits derived from classical tradition, and are also frequently represented by the symbols which originate from the four "
living creatures" that draw
the throne-chariot of God in the vision in
Ezekiel 1 reflected in the
Book of Revelation (ff), referred to as the four '
Seraphim', though neither source links the creatures to the Evangelists (of course the depiction of the Seraphim predates in chronology the writing of the New Testament which portrays the writers John, Luke, Mark, Matthew as symbolically embodied by the four Seraphim). Images normally, but not invariably, appear with wings like
angels. When the symbols of the Four Evangelists appear together, it is called a
Tetramorph, common in the
Romanesque art of Europe such as church
frescoes or
murals. The meanings accruing to the symbols grew over centuries, with an early formulation by
Jerome, When surrounding Christ, the figure of the man usually appears at top left—above Christ's right hand, with the lion above Christ's left arm. Underneath the man is the ox and underneath the lion is the eagle. This both reflects the medieval idea of the order of "nobility" of nature of the beasts (man, lion, ox, eagle) and the text of
Ezekiel 1:10. From the 13th century, their use began to decline, as a new conception of
Christ in Majesty, showing
the wounds of the Passion, came into use. In Evangelist portraits, they sometimes appear to dictate to the writing evangelist. ==Naming==
