Indra Otsutsuki had the Mangekyo Sharingan. It was not unknown. Madara and Izuna were just the first Uchiha to unlock it. Hagoromo also had the Mangekyo. So Hagoromo was the first to activate the Mangekyo. But he mostly used his Rinnegan, so his eyes never took that much damage.

And Madara did take Izuna's eyes. I feel as though you're not thoroughly reading these replies.

EDIT: That came off harsher than I intended. What I mean is:

EMS was unknown. Indra had Mangekyo but he did not have EMS. That's what was stated.

Hagoromo only ever had the Sharingan in the anime. And in the anime, his eyes went straight from Sharingan to Rinnegan.

Yes Madara took Izuna's eyes, after Izuna offered them since he himself was dying
