Contrary to popular belief no mention of the fruit being an apple can be found in the Book of Genesis.
Jewish commentaries recorded in the Midrash Rabbah speculate that the tree might have been a species of wheat, or corn, or that the fruit might have been grapes or figs.
And yet, the idea that it was an apple is widely accepted.
Was it due to Classical influences (The golden apples in the Garden of the Hesperides)?
Is it a legacy from the Latin 'malum' (apple/evil)?
Or is there another reason?
Are there any other theories that have been put forward as to what the fruit might have been?
