Windows let you see in and out.
In ancient times they were small, and deep;
a potential weak point in a wall.
But necessary, one had to be able to see,
With high windows to the North, South, East and West.
There were four levels, reached by ladders, inside.
In fact, you couldn’t even get in without a ladder–
the door is 12.5 feet up from the ground.
One can imagine the monks and students
fleeing to the tower when the Vikings came rampaging.
The story of Rapunzel becomes plausible.
And this proverb:
The name of the Lord is a strong tower,
the righteous run to it and are safe.
Nantucket’s towers have 360 degree windows:
To shine into the night,
warning of treacherous shoals.
And to show the way home.
