This map outlines the essentials of Leigh Brackett’s fantastic Mars. Heinlein’s poem below explains what that world is like.
And you find more of my thoughts on the subject in a series of posts here — link >>>
As Time and Space come bending back to shape this star-specked scene,
The tranquil tears of tragic joy still spread their silver sheen;
Along the Grand Canal still soar the fragile Towers of Truth;
Their fairy grace defends this place of Beauty, calm and couth.
Bone-tired the race that raised the Towers, forgotten are their lores;
Long gone the gods who shed the tears that lap these crystal shores.
Slow beats the time-worn heart of Mars beneath this icy sky;
The thin air whispers voicelessly that all who live must die —
Yet still the lacy Spires of Truth sing Beauty’s madrigal
And she herself will ever dwell along the Grand Canal!
