"Shakespeare" wrote the play "Julius Caesar" to exemplify the passion of envy, and it was first published in 1623.
Is it a coincidence that in 1625 Francis Bacon wrote an essay on envy, every point of which is illustrated and enforced in "Shakespeare's" play; the play and the essay both expressing the same sentiments, and being published for the first time several years after Shaksper's death?
