The corresponding Maya day is Men, associated with the eagle and, in some colonial sources, with the aged moon goddess and with the craft of building; the Aztec equivalent day is Cuauhtli, eagle. The eagle in Mesoamerican thought is a solar and celestial bird, paired with the jaguar as the two great predator emblems of warrior orders in central Mexico. Modern K'iche' practice reads the corresponding day Tz'ikin, bird, for fortune, for money and for the intermediary between earth and sky. The Dreamspell reading of vision and mind picks up the eagle's height and sight, which is a reasonable extension, though again it is a modern reading and not a report of Maya doctrine.
Men is the fifteenth of the twenty authentic Tzolk'in day signs, its imagery the eagle and vision, both literal eyesight and, by extension, foresight; the living K'iche' daykeeping tradition knows the corresponding day as Tz'ikin, the general K'iche' word for bird. In the directional scheme, Men belongs to the west and the colour black. Arguelles's Solar Seal 15, Blue Eagle, borrows Men's eagle and vision imagery closely, one of the more direct name-borrowings in the system, though the substitution of blue for the traditional black remains original to the Dreamspell's own colour scheme.
