The designation “Corinthian (horse)” does not correspond to a widely recognized or documented individual horse in major equine or sporting references. No substantial entries, race records, or historical accounts in authoritative databases (such as The Jockey Club, Racing Post, or major encyclopedias) have been located that verify the existence of a notable horse bearing this exact name.
The term may arise from a descriptive use of the adjective “Corinthian,” which historically denotes something related to the ancient Greek city of Corinth or, in sporting contexts, a gentleman amateur. It is plausible that a horse could have been informally or locally named “Corinthian,” but without verifiable sources, detailed information about its breeding, racing career, or achievements cannot be confirmed.
Accurate information is not confirmed.
