Footnote to the article “The Founding of Alexandria” by Walter Johannes Stein

Das Goetheanum, 4th year, No. 1

...If you desire to endure forever in eternal youth, found the glorious city on Proteus' island realms, Which mightily protect the Plutonean deity, On five-peaked heights the infinite universe directing.

What is meant is that the city should be founded in such a way that the continued effect of the forces present in it is made possible. This can only happen if the forces of the earth (Plutonic forces) are guided by the forces of the cosmos (the forces of the five planets) in a rhythmic sequence through the course of historical time.
