intimately associated with sun worship, yet which were at first 
but survivals of the round medicine lodge. 
(2) The rainbow is a deified animal having the attributes of 
a human being, yet also the body and some of the functions of 
a measuring worm Obviously, the striped back and arched 
attitude of the measuring worm, its sudden appearance and 
disappearance among the leaves of the plants which it inhabits, 
are the analogies on which this personification is based. As 
the measuring worm consumes the herbage of the plants and 
causes them to dry up, so the rainbow, which appears only after 
rains, is supposed to cause a cessation of rains, consequently 
to be the originator of droughts, under the influence of which 
latter plants parch and wither away as they do under the 
ravages of the measuring worms. Here it will be seen that the 
visible phenomenon called the rainbow gets by analogy the 
personality of the measuring worm, while from the measuring 
worm in turn the rainbow gets its functions as a god. Of this 
the cessation of rain on the appearance of the rainbow is ad- 
duced as proof, and the incidents of the myth history of the 
rainbow gods are, as might be shown by additional illustration, 
but further dramatizations of these functions of the measuring 
worm. So much indeed is this the case that the fading of 
flowers is attributed to the rainbow, who, consuming their 
imperceptible existences, thus derives his brilliant coloring just 
as it is believed that the measuring worm gets his green, yel- 
low, and red stripes from the leaves and flowers which he de- 
vours. The influence of all this analogie philosophy is shown 
in the Zuni theogony and worship by the way in which the 
rainbow is relegated to a place among the malignant gods of 
war—hence painted on war shields—and made a demon to be 
propitiated, yet shunned. Therefore he is unhonored in the 
worship of the Zuni, turned from by them when he appears 
in the sky, and covertly imprecated in set formule. 
The general conclusions from these examples may be that 
in folk myths natural phenomena become personified, mostly 
by visible analogy, while functions become dramatized, but
