I am a bit confused by the Seiken Densetsu timeline

First of all, pardon me for using the Japanese name of the series as I don’t know why, but I wanted to make it easy to understand as something about it I am confused by is where Seiken Densetsu 3 is set in the timeline of the original trilogy as while I did play the Super Famicom version briefly, I wasn’t sure if it was a prequel to the other games.

I mean, correct me if I am wrong, but the third one is set 1000 years into the past before the second Mana game as so far, my experience with the Mana games is with the first two ones as those are the only ones I have ever beaten as I did beat the second one way back on the SNES version, and the first one via the original Game Boy version, but I was a bit confused by the third one regarding the chronological order it goes by.
