18th/21 Periods of the Cosmos, the 4th/7 Period of Released Creation is the Biblical Day-period of the Celestial Relationships and Biological Cycles Age; the Proterozoic Eon covering the period of time of BC AYN 2,467,592,696 through BC AYN 541,952,697.
10th/12 simple or elemental (פשוטות) letters (ספרים) of He (ה) symbolizes the Biblical Day-period of the Celestial Relationships and Biological Cycles Age beginning with Genesis 1:16: "two great lights; the greater light to rule the day and the lesser light to rule the night." The greater light or direct light being the Sun and the lesser light or indirect reflected light being the Moon. The ruler or god of day and the ruler or god of night.
Earth had to set the pattern of the biological clocks that underlie the life cycles of all living forms on Earth. The Earth had to settle into its orbital and rotational patterns and be subjected to the effects of the Sun and the Moon, which were primarily manifested in the cycles of light and darkness. The Book of Genesis assigns the fourth “day” to this organization and to the resulting year, month, day, and night repetitious periods. Chronobiology is a field of biology that examines periodic (cyclic) phenomena in living organisms and their adaptation to solar- and lunar-related rhythms. Only then, with all celestial relationships and cycles and their effects firmly established, did the creatures of the sea, air, and land make their appearance in Day-period 5.
According to Aztec mythology the 13 heavens (8th-20th Periods of the Cosmos) filled the head of Cipacli the Aztec monster goddess of creation similar to the Sumerian goddess of creation called Tiamat. Imix (עמיק) is the Yucatec for the Kaqchikel Imox (עמוק). Imix (עמיק); (to cause to make) deep" and Imox (עמוק); "to be deep" or "deepening" are the same Hebrew root-stem IMK (עמק); "deep," the same semantic meaning as the Hebrew root-stem of the Sumerian creature Tiamat (תהום); "deep" or "depths."
