Standish James O'Grady (Irish: Anéislis Séamus Ó Grádaigh; 18 September 1846 – 18 May 1928) was an Irish author, journalist, and historian. O'Grady was inspired by Sylvester O'Halloran and played a formative role in the Celtic Revival, publishing the tales of Irish mythology, as the History of Ireland: Heroic Period (1878), arguing that the Gaelic tradition had rival only from the tales of Homeric Greece.
