A rainbow appears once a heavy storm has passed, color arcing across a sky recently emptied of the weather that produced it, an old and widely shared sign read across many traditions as a promise rather than a threat. Mars continues to rule both decan and term. Wheeler produced this image in the 1925 Balboa Park session; the reading here, naming a link between what is above and what is below, a covenant with one's own divine nature, and a promise of immortality, is Rudhyar's 1973 language, and it reaches for explicitly religious vocabulary, covenant specifically, that draws on a long tradition of reading the rainbow as a pledge rather than as simple optical weather.
There is little shadow offered for this one, though a promise this large, arriving after hardship rather than instead of it, still depends on the storm having actually happened first; the rainbow is not available without it. Leo, ruled by the sun that makes the rainbow visible once the rain has cleared, closes in on the sign's final degrees with a symbol of assurance following difficulty, an answer to the very storm that opened this same run of degrees just ten places earlier. The image also asks nothing of the viewer beyond noticing it, no ritual, no ceremony, just a sky doing on its own what skies after storms have always done, available equally to whoever happens to be looking up at the right moment.
