“Three choir spandrels in the wall before me tell the story of the Fall and the Redemption. In the center spandrel is ‘Adam in the Garden.’ his look suggesting he sees what’s about to happen. To his right an angel is attempting to thwart Satan, who, in ‘The Temptation,’ the right-hand spandrel, is shown in mosaic as a handsome but frightening winged figure. He points to the forbidden fruit with his right hand while gesturing with his left to someone to be silent. It’s Eve, naked but for adornment in her golden hair, a gold so preciously metallic that I wonder at its karat - it’s so exquisite as to be the envy of any blonde beholding it.
Toward the nave is ‘The Expulsion,’ in which the archangel with his sword of light is driving the first couple out of the garden. Adam, a fig leaf now firmly in place, loops his arm over the bent neck of Eve. But the fallen Eve is changed - she’s cowering, now, under the weight of her long, red hair.
...in any accounting for how the problems of evil came to fall on the heads of humanity forever after, there would need to be a traceable source, a scapegoat, which is how Eve is portrayed in the mosaics. She is seen carrying the stain of sin - the original sin - much as the red hair of her son Cain will later mark his own fall from grace.” ~ Marion Roach, The Roots of Desire, p165-66.
