I discovered that “face” in Matthias Grünewald’s painting in 2018, but perhaps I was not the first one. I think that Gustave Doré found it already in the year 1863 when looking for inspiration from other artwork.
Two illustrations by Gustave Doré (rendered in mirror view):
※ Left: Illustration to John Milton’s Paradise Lost, Book VI, 1866.
※ Right: Illustration Plate I to chapter 1 in Miguel de Cervantes’ Don Quixote, 1863 edition.
※ Left: Illustration Plate I (mirror view) to chapter 1 in Miguel de Cervantes’ Don Quixote, 1863 edition.
※ Right: Matthias Grünewald’s Temptation of St Anthony (c. between 1512 and 1516, a panel of the Isenheim Altarpiece, now located at Museé Unterlinden, Colmar, France).
