Cronos (Κρόνος) was the leader of the Titans and their order. In the Theogonia and the Titanomachia the fall of the titans and the rise of the Olympian order with Zeus as the head (Zeus was the son of Cronos) is argued to be something similar to the archetypical night-darkness against daylight progression (which is also a previous part of the Theogonia itself, with Night, Erebus, and Chaos, being the first existences according to Hesiod).
It is also notable that Cronos was still tied to any barbaric activity, and most notably irrational killing or even human sacrifice. So a number of foreign gods- particularly in the early Hellenistic era- were tied to Cronos by the concurrent Greek historians and other thinkers, such as the Phoenecian Baal deity and the sacrifice of children in the idol-oven of Baal, or the Getae deity Zamolxis, who asked an annual rite of a Getae warrior to be thrown to three spears, having first been told what to ask Zamolxis upon meeting with him in the afterlife..

I wanted to ask if there are any reputable studies, particularly with foundations on the classic era, regarding the origins of the Cronos/Saturn deity and their order of darkness and death. Some argue the order was a symbol for a pre-archaic human-sacrifice era in the Greek world (prior to Homer, so i suppose at around 1000 BC or before that), but i have not seen any definitive study.
I also have seen it argued that Cronos is a slight alteration of the term Chronos (Greek term for Time), and this would tie things to Anaximander's claim that Time asks all finite things to return to the infinity from which they came, and be decomposed there once more.
