Full title: The Castle of Otranto, A Story. Translated by William Marshal, Gent. From the Original Italian of Onuphrio Muralto, Canon of the Church of St. Nicholas at Otranto

On the day of his wedding, Conrad, the frail heir of Manfred, Prince of Otranto, is crushed in the castle courtyard by a gigantic helmet that has fallen from nowhere. Manfred, haunted by an old prophecy that his family will lose Otranto, resolves to put aside his wife Hippolita and marry Conrad’s bride, the young Isabella, himself. She escapes through the vaults beneath the castle. In the days that follow, a portrait steps out of its frame, a statue bleeds, and a peasant named Theodore troubles the household with a face it seems to know. Walpole sets a medieval Italian court against the claims of lineage and succession, and makes the stones themselves protest.

he beheld his child dashed to pieces, and almost buried under an enormous helmet, an hundred times more large than any casque ever made for human being, and shaded with a proportionable quantity of black feathers.

Attribution and scope

First edition pseudonymous: presented as a translation by ‘William Marshal, Gent.’ of a work by ‘Onuphrio Muralto’; both names are invented. Walpole acknowledged authorship in the second edition, whose title adds the subtitle ‘A Gothic Story’.

Facts

  1. The first edition was issued on Christmas Eve, 24 December 1764, although its title page is dated 1765. It appeared without Walpole’s name, and he acknowledged authorship in the second edition about six months later.[1][2]
  2. The first Preface invents a pedigree: the story is said to have been printed in black letter at Naples in 1529 and found in the library of an old Catholic family in the north of England, and the title page credits a translator, ‘William Marshal, Gent.’, who did not exist.[3][1]
  3. Walpole traced the story to a dream in which he thought himself in an ancient castle and saw a gigantic hand in armour on the uppermost banister of a great staircase; he began writing that evening and, according to the edition’s biographical introduction, finished it in two months.[3]
  4. The second edition was the first to carry the subtitle ‘A Gothic Story’, so the word ‘Gothic’ was applied to the novel by Walpole himself.[2][1]

Setting

Between the First Crusade (1095) and the last Crusade (1243), as the first Preface reckons it[3]

  1. Date: the title page is dated 1765 but the book was issued on 24 December 1764 (Soane Museum, CSUN). The timeline anchors on 1764, the year of first public appearance.
  2. Second-edition month: the Soane record says ‘six months later’; no authoritative source names the month, so only 1765 is shown.

  • Its tradition continues in The Mysteries of Udolpho 1794

    The Dictionary of National Biography’s entry on Lewis calls Radcliffe’s romances a form of literature of which Walpole’s Castle of Otranto ‘set the first example’; a genre-level link, not a documented borrowing.[4]
