Hence to the Aztec astronomer and sage, the house of the sun is always

twin sister (the morning twilight), he wasted his life in noting the
likeness of his own features to those of his beloved who had passed away.
"The sun, as he looks down upon his own face reflected in a lake or sea,
sinks or dies at last, still gazing on it."[1]

Nevertheless, there is another myth which countenances this view and
