Stromboli and Homer
Man77 - CC3.0
In a canto of the Odyssey, Homer describes Stromboli as surrounded by a copper wall that makes it impregnable:
We arrived in Aeolia, where the delight
To the immortal gods of Hippotas son,
Aeolus, lived on a floating island,
Which includes a whole wall of unbreakable copper
And a smooth surrounding lofty cliff. "
(Odyssey, X) Homer
Stromboli appears very high, steep and steep to navigators, like a wall with the sea around it.
