Pantomath is typically used to convey the sense that a great individual has achieved a pinnacle of learning, that an "automath" has taken autodidacticism to an endpoint. As an example, the obscure and rare term seems to have been applied to those with an astonishingly wide knowledge and interests by these two authors from different eras: G. M. Young has been called a pantomath,[2] as has Rupert Hart-Davis.[3]
