"Ibid" is a parody by American horror fiction writer H. P. Lovecraft, written in 1927 or 1928, and first published in the January 1938, issue of O-Wash-Ta-Nong.

[1][2] "Ibid" is a mock biography of the Roman scholar Ibidus (486–587), whose masterpiece was Op.

The piece traces the skull of Ibidus, once the possession of Charlemagne, William the Conqueror and other notables, to the United States, where it travels via Salem, Massachusetts and Providence, Rhode Island to a prairie dog hole in Milwaukee, Wisconsin.

The story is prefaced with the epigraph "'...As Ibid says in his famous Lives of the Poets.'

But S. T. Joshi and David E. Schultz report that the "target of the satire in 'Ibid' is not so much the follies of students as the pomposity of academic scholarship.
