"The 1902 book Judah's Sceptre and Joseph's Birthright by J. H. Allen is a British Israelist tract that is cited by scholars as one of the reasons why U.S. white supremacists discovered British Israelism and twisted it into the explicitly racist Christian Identity theology."

"Christian Identity...is a racist, anti-Semitic, and white supremacist interpretation of Christianity which holds that only Germanic, Anglo-Saxon, Celtic, Nordic, Aryan people and those of kindred blood are the descendants of Abraham, Isaac and Jacob and hence the descendants of the ancient Israelites..." (“Christian Identity.” Wikipedia, Wikimedia Foundation, 4 June 2019, en.wikipedia.org/wiki/Christian_Identity.)

Muiris O’Sullivan considers the British Israelite vandalism at the Rath of the Synods to be "reminiscent of Schliemann's search for ancient Troy," which occurred only 20 years earlier. (O'Sullivan, Muiris, Michael Herity, and Ursula Mattenberger. Duma na nGiall: the Mound of the Hostages, Tara. Bray, Co. Wicklow: Wordwell, 2005, p. 9.)

Schliemann used ancient literature (Homer) as his guide, similar in some ways to the British Israelites using their eccentric reading of the Bible and mythology to create their own blueprint for excavation. Schliemann, who deployed dynamite in his excavations and was not above smuggling artifacts out of the country, may have served as an inspiration for the British Israelites. Schliemann also "discovered," and introduced to the West the ancient symbols that was to evolve into the Nazi swastika, finding "...on shards of pottery and sculpture at least 1,800 variations on the same symbol..." (Boissoneault, Lorraine. “The Man Who Brought the Swastika to Germany, and How the Nazis Stole It.” Smithsonian.com, Smithsonian Institution, 6 Apr. 2017, www.smithsonianmag.com/history/man-who-brought-swastika-germany-and-how-nazis-stole-it-180962812/.) Given the evolution of the British Israelites into the racist Christian Identity movement, it is illustrative that books on ancient monuments, and Irish antiquarian T.J. Westropp made use of the symbol. As seen in this composite illustration, Westropp, in his 1910 plan of Dún An Óir adopted as his symbol the vertical swastika (circled in red) noted in many ancient cultures, such as uncovered by Schliemann. But a couple of decades later, the archaeologist's swastika had taken a sinister turn, literally, into the Nazi symbol, as seen on the cover of the 1935 pamphlet by Charles Diot which discusses the prevalence of the symbol within megalithic monuments. (Diot, Charles. Les Sourciers et les Monuments Megalithiques. Bourg: Imprimerie Berthod, 1935.)

Irish Archaeologist Robert Chapple's slide lecture illustrates the origins of the swastika in Irish art and archaeology.
