The Chronicles of Creation in Diablo 4 are basically the equivalent of the Altars of Lilith in the base game, except for the isles of Skovos. That means they're a great way of quickly farming up Renown and so unlocking the bonus skill and paragon points you can get via that currency's reward track.
These statues are a little more puzzly than Lilith's altars, though, since they require you to track down Weathered Shrines and then connect two other statues to them. Obviously, this guide will contain spoilers for the Skovos map, since I'm displaying the Chronicles of Creation locations across each isle, but otherwise, here's how they work and where to find them.
How to use Weathered Shrines in Diablo 4

If you run across a Weathered Shrine in Diablo 4, you've found a Chronicle of Creation in-waiting. All you need to activate it, as the riddle on the shrine implies, is find a statue of Lilith and a statue of Inarius in the nearby area and turn them each to face the shrine, which will create a beam of light connecting them.
Once done, interact with the shrine to complete that Chronicle of Creation, earning XP and Renown for each. Similarly, if you find a statue of Inarius or Lilith, you can turn them till they emit the beam of light, and then follow it to find the shrine in question. Some of these were bugged for me, but I simply portalled back to Temis and returned to re-activate them.
Diablo 4 Chronicles of Creation locations
There are 30 Chronicles of Creation hidden across Skovos, which, for the most part, averages out at five for each island. I'm currently missing two since there only seem to be three statues on Athulua and I've explored each island thoroughly, plus the strongholds.
When I do find them, though, I'll make sure to add them. Otherwise, here are the locations for each island, marked with the statue symbols, in order of when you can access them:
Philios Chronicles of Creation locations

There are five Chronicles of Creation on Philios.
Lycander Chronicles of Creation locations
