When was the name of the sage of six paths mentioned?

[Sefirosu Masamune]

"Hagoromo Ōtsutsuki (大筒木ハゴロモ, Ōtsutsuki Hagoromo), known to the world at large as the Sage of the Six Paths (六道仙人, Rikudō Sennin), was a legendary god-like figure who founded the arts of ninjutsu and created the ninja world. He was the son of Princess Kaguya Ōtsutsuki‎‎ and the first human to be born with chakra. He defeated the Ten-Tails in battle and sealed the beast within his own body, thus becoming the very first jinchūriki in history."
-Narutopedia

The naruto wiki site naruto pedia is rarely wrong when it comes to naruto information. this is the first paragraph about the sage of six paths. my question is where did the name Hagoromo Otsutsuki come from? was it mentioned in the manga and did i miss it or what???
