A symbolic example of (60558) Echeclus is the precovery process, were the discovery image of an astronomical objects is tracked back in old archived images:
"Precovery (short for "pre-discovery recovery") is a term used in astronomy that describes the process of finding the image of an object in old archived images or photographic plates for the purpose of calculating a more accurate orbit. The name is based on pre-discovery recovery; recovery being the process of making new observations of a previously observed object after a period of non-observation. This happens most often with minor planets, but sometimes a comet, a dwarf planet, or a natural satellite is found in old archived images; even exoplanet precovery observations have been obtained." (Wikipedia)
An example in astrology is the aspects in the cycle of two planets, or the Age Point aspects cycle to a birth planet from one conjunction to the next one, or the threefold contacts of a planet in retrograde transit.
This repeated in and out through time, gives a wide time perspective. The chase of this interconnected moments is one of the best methods in astrological investigation.
The book "Life Clock: Huber Method of Timing the Horoscope" (Bruno & Louise Huber, 1980) appeared during the prediscovery of (60558) Echeclus.
