In an extraordinary triumph of the human mind, the planet Neptune was discovered in Berlin, Germany, not through visual scanning, but via pure mathematical calculation. Astronomers Urbain Le Verrier and John Couch Adams independently noticed weird gravitational anomalies in the orbit of Uranus and calculated exactly where an undiscovered planet had to be. When Berlin stargazers pointed their telescopes at the predicted coordinates, the planet was found within one degree of the mathematical prophecy.

This mind-boggling scientific prophecy deeply shook Victorian writers, igniting a wave of cosmic and philosophical poetry regarding the invisible laws of nature. It heavily influenced the Transcendentalist poets and later symbolists, who used Neptune as an enduring metaphor for hidden truths that can only be seen through intellect and intuition.
