When I Heard the Learn'd Astronomer
How we cite our quotes:
In the mystical moist night-air, and from time to time,
Look'd up in perfect silence at the stars. (line 7-8)
"Mystical" is the most important word relating to spirituality in the poem. "Mystics," like prophets, are spiritual figures who commune directly with God or the divine. The night air creates a mystical atmosphere in which the human speaker feels "at one" with his natural surroundings.
