Libra 4. By accident, a man finds an invisible tower.
Glad he’d been walking so slowly, admiring the vista, for he ran into it, bumping his forehead.
He felt for and found a door. He noticed the steps were made of wind, sturdier than one might think, and circular. He ascended so high the sky grew black, but he could still breathe – a little piece of blue sky had followed him up, enveloping his head like a cloudless aurora.
Looking out he viewed the curvature of the earth, cities and seas. A miraculously stable tower, at least for the moment. He called it the Great Antiquity of the Present.
