THE CALENDAR
The Conflict between Light and Darkness
We witness in the Maya mythology a dualism almost as complete as that of ancient Persia—the conflict between light and darkness. Opposing each other we behold on the one hand the deities of the sun, the gods of warmth and light, of civilisation and the joy of life, and on the other the deities of darksome death, of night, gloom, and fear. From these primal conceptions of light and darkness all the mythologic forms of the Maya are evolved. When we catch the first recorded glimpses of Maya belief we recognise that at the period when it came under the purview of Europeans the gods of darkness were in the ascendant and a deep pessimism had spread over Maya thought and theology. Its joyful side was subordinated to the worship of gloomy brings, the deities of death and hell, and if the cult of light was attended with such touching fidelity it was because the benign agencies who were worshipped in connection with it had promised not to desert mankind altogether, but to return at some future indefinite period and resume their sway of radiance and peace.
The Calendar
Like that of the Nahua, the Maya mythology was based almost entirely upon the calendar, which in its astronomic significance and duration was identical with that of the Mexicans. The ritual year of twenty "weeks" of thirteen days each was divided into four quarters, each of these being under the auspices of a different quarter of the heavens. Each "week" was under the supervision of a particular deity, as will be seen when we come to deal separately with the various gods.
