SIN OR HURKI
is the name of the moon deity; the etymology of it is quite uncertain. Its titles, as Rawlison remarks, are somewhat vague. Yet it is particularly designated as “the bright, the shining” the lord of the month.
Zin in Maya has also many significations. Zin is to stretch, to extend. Zinil is the extension of the whole of the universe. Hurki would be the Maya Hulkin—sun-stroked; he who receives directly the rays of the sun. Hurki is also the god presiding over buildings and architecture; in this connection he is called Bel-Zuna. The lord of building, the supporting architect, the strengthener of fortifications. Bel-Zuna would also signify the lord of the strong house. Zuú, Maya, close, thick. Na, house: and the city where he had his great temple was Ur; named after him. U, in Maya, signifies moon.
