Examines the contrasting symbolism and imagery of perpendicular structures (mountains, trees, built structures, and so on) and waves in the Space Trilogy as a whole. Eddings finds more than simple gendered symbolism in these clusters of images; verticality indicates reaching for the heavens and waves show submission to the will of Maleldil. These symbols are reconciled in the arches of the temple Tor plans to honor Maleldil in Perelandra.
