Who threw the plate in that made the Egel Zahav עֵגֶל זָּהָב come out?

Question

Yehuda haKohen relays:

The Hebrew worldview associates Yosef with cattle. In Moshe’s brakhot to the different tribes at the end of Sefer D’varim, we see Yosef likened to a shor – a bull. Our Sages teach that when Moshe raised Yosef’s sarcophagus from the bottom of the Nile, he had written the words “aleh shor” – “arise bull” on a metal plate and then cast that plate into the river. Yosef’s body then rose to the surface and Moshe was able to fulfill the nation’s oath to bring it with us out of Egypt.

The Midrash Tanḥuma teaches that someone retrieved this metal plate and brought it to Sinai. When the people demanded that Aharon construct a new god to replace Moshe, Aharon collected their gold and began to melt it down. Then this man threw the metal plate with the words “aleh shor” into the fire and the Golden Calf emerged.

Who was this man who inherited the golden plate and caused the golden calf to emerge? What was his name?

Answer 1

His name was Michah, per Midrash Tanchuma, cited by Rashi to Shemos 32:4:

There are some who say that Micah the idolator mentioned in Judges ch. 17, was there, who had been drawn forth from the foundations of a building in Egypt where he was nearly crushed. He had in his possession a “supernatural name” (שם) and a plate upon which Moses had written: “Come up, ox, come up, ox!” in order to raise the coffin of Joseph who is compared to an ox (cf. Deuteronomy 33:17) out of the Nile, and he cast it (the plate) into the melting pot and the calf (the young ox) came out (ויצא העגל הזה) (Midrash Tanchuma, Ki Tisa 19).
