The Non-Christian Cross-An Enquiry into the Origin and History of the Symbol Eventually Adopted as That of Our Religion is a classic religious studies text by John Denham Parsons. In the thousand and one works supplied for our information upon matters connected with the history of our race, we are told that Alexander the Great, Titus, and various Greek, Roman, and Oriental rulers of ancient days, "crucified" this or that person; or that they "crucified" so many at once, or during their reign. And the instrument of execution is called a "cross."
