Yet why do I talk to you of the Greeks? Even the Indians, when they get up in the morning and pray to the sun, instead of doing as we do, who think that when we have kissed our hand the prayer is complete, face the sunrise and welcome the God of Day with dancing, posturing in silence and imitating the dance of the god; and that, to the Indians, is prayer and dance and sacrifice all in one. So they propitiate their god with those rites twice each day, when it begins and when it declines.
The Ethiopians, moreover, even in waging war, do it dancing, and an Ethiopian may not let fly the shaft that he has taken from his head (for they use the head in place of a quiver, binding the shafts about it like rays) unless he has first danced, menacing the enemy by his attitude and terrifying him in advance by his prancing.Heliodorus i in the La opica (IX, 19) goes into greater detail. Cf. also H. P. L’Orange, Symbolae Osloenses XII (1934), 105-113, who calls attention to representations of Roman auxiliaries with arrows bound to their heads in the frieze of the Arch of Constantine.
