In Paradise Lost, John Milton references Lebanon in the context of one of the fallen angels Tammuz, (an early archetype for the dying-and-rising god) whose "annual wound" in Lebanon caused damsels to mourn.
The "Adonis" river that runs through Lebanon was said to run purple with Tammuz blood, representing idolatry that seduced followers from God.
Adonis, in Greek mythology, represents extreme male beauty.
Milton uses this description to highlight the seductive danger of idolatry that lures people away from the "sacred porch," a key theme of disobedience in the poem's early books.
Oh beautiful Adonis, born from a cursed, incestuous union…
A mortal hunter who was gored and killed by a wild boar during a hunting trip…
