There is a mixture of 2 mithraeums in the text. The first part and the inscriptions are about mithraeum of Victorinus (II.) But the altars in the mithraeum are just copies and unfortunatelly there was no tauroctony found there at all. The fragment in the Lapidarium is from different place so wikipedia is false. The video and the description are about the Symphorus mithraeum (IV).
This marble basin found in the Mithraeum of the Footprint bears an inscription of a certain Umbilius Criton, associated with a monumental tauroctonic sculpture also found in Ostia.
