This Roman altar, now in Tresco Abbey Gardens, was originally found in a well at Mount Holles on the island of St Marys. The urn and other rocks were cemented on when the altar was moved to the Gardens. The altar contains Mithraic-style symbology - an axe on one side and a cleaver on the other. It is otherwise uninscribed. This 3D scan is rather low-quality, captured opportunistically with an iPhone. It is possible that the faint markings of an inscription, or the beginning of one is visible, but this would warrant further investigation. The matcap shader - accessed from the Rendering icon - shows the detail well (and exposes the poor quality of the mesh). Source: Objaverse 1.0 / Sketchfab
