Oliver St. John

It seems “Oliver St. John” can refer to more than one person depending on context. Two notable individuals emerge:

  1. Oliver St. John Gogarty (1878–1957) — Irish poet, physician, author, and politician.

  2. Oliver St. John (1598–1673) — English judge, statesman, and politician.

There is also a modern esoteric / occult author using the name Oliver St. John, whose works include metaphysics, ritual magic, and related fields.

Which “Oliver St. John” did you mean — Gogarty, the English judge, or the esoteric author — or someone else entirely? Once you confirm, I’ll prepare a full SEO-optimized article.
