Meaning of cuartos de luna by Felipe Lorenzo del Río

Although this is a truism, the moon are four, i.e., the appearance of the Moon from the Earth passes through four phases or States every 28 days we call: Moon fills, moment in which we see round, in all its fullness, but the next day begins to wane and starts the last quarter until desapadecer, now called new moon. The next day it starts to see again and start the Crescent until reaching their fullness. And the cycle continues. Now, when we see the Moon any day would know if it is quarter growing or shrinking?. A trick that already the ancients knew is that the Moon is lying: when C-shaped, not grow but decreases, and when have forms of D, not decrease but grows. In Castile in the past also said: waxing, horns pa '' l Middle East; last quarter, pa front horns.
