The ancient Greeks, ancient Romans and ancient Christians all had different concepts of the planetary sky gods. The king of the gods was known by different names. To the Greeks he was Zeus, to the Romans he was Jupiter and to the Christians he was Jesus.
The word chronometer means clock or timepiece and this god was a divider of time and space. To the Greeks he was Kronos, the Romans he was Saturn and to the Christians he was Satan.
Since the Sun enters Capricorn at Christmas-time, Santa becomes an anagram for Satan (move the n).
