John Chetwode Eustace

John Chetwode Eustace (c. 1762 in Ireland – 1 August 1815 at Naples, Italy) was an Anglo-Irish Catholic priest and antiquary.

This was an unusual position for a Catholic priest, and Eustace's intercourse with leading members of the university led to his being charged with indifferentism.

John Milner, then vicar Apostolic, charged him with laying aside "the distinctive worship of his priesthood".

In 1813 the publication of his "Classical Tour" obtained for him sudden celebrity, and he became a prominent figure in literary society.

A short tour in France, in 1814, led to his "Letter from Paris", and in 1815 he travelled again to Italy to collect fresh materials, but he was seized with malaria at Naples and died there.
