Below, an artist's rendering of an ivory box found at Late Bronze Age Megiddo, Israel. The missing heads of the Cherubim/Winged Sphinxes have been "restored" in the drawing. Note that the heads of the Lions and Cherubim "are turned" in this Phoenician late 13th century BCE creation. I have utilized the concept of the "turned face or head" to show the two Cherubim flanking the Mercy Seat atop the Ark of the Covenant "as facing each other" as described in Holy Writ.
Exodus 37: 9 RSV
"The cherubim spread out their wings above, overshadowing the mercy seat with their wings, with their faces one to another; toward the mercy seat were the faces of the cherubim."
