Allegro served in the
Royal Navy during
World War II, began training for the
Methodist ministry but shifted to
Oriental Studies, earning degrees from
Manchester and
Oxford before joining the Dead Sea Scrolls research team in
Jerusalem and becoming a lecturer in
Semitic Philology in 1954. He played a pivotal role in the early study and popularization of the
Copper Scroll by arranging its physical opening, producing the first translation, controversially publishing it ahead of the official edition, and promoting theories about its content that drew criticism from his peers. Among his most significant contributions was his work on the Copper Scroll, a unique document inscribed on copper sheets that described the locations of hidden treasures, which Allegro was the first to translate and publish in 1960. By 1960, Allegro, holding controversial views on the Dead Sea Scrolls and clashing with colleagues, moved to theology at Manchester where he wrote the provocative book
The Sacred Mushroom and the Cross and subsequently resigned due to its impact. His volume was published in 1968 as part of the
Discoveries in the Judaean Desert series, using what he described as a minimalist editorial approach. While he was in England he made a series of radio broadcasts on
BBC Radio aimed at popularising the scrolls, in which he announced that the leader discussed in the scrolls may have been crucified. (a position that he re-iterated in 1986). His colleagues in Jerusalem immediately responded with a letter to the Times on 16 March 1956 refuting his claim. However, in July after several uneasy months the appointment was renewed. Allegro was asked a number of times by the Jordanian Director of Antiquities if he would publish the text of the Copper Scroll. After a few years of waiting for Milik's publication of the scroll, Allegro succumbed and set about publishing the text. His book,
The Treasure of the Copper Scroll, was released in 1960, while the official publication had to wait another two years. Although several of his readings in the text are acknowledged, Allegro's book was disparaged by his colleagues. He believed that the treasure in the scroll was real—a view now held by most scholars and published several preliminary editions in learned journals during the late 1950s. He told de Vaux that he could have his share of the texts ready in 1960, but due to hold ups had to wait until 1968 for his volume,
Discoveries in the Judaean Desert of Jordan V: 4Q158–4Q186, to be published. He reworked his material in 1966 with the assistance of a Manchester colleague, Arnold Anderson, before publication.
John Strugnell published a severe critique of the volume, "Notes en Marge du volume V des 'Discoveries in the Judean Desert of Jordan'" in
Revue de Qumran. Allegro's minimalist approach has received widespread scorn in the scholarly world, which nevertheless had the opportunity to analyse the Allegro texts for decades while waiting for other editors to publish their allotments. The first part of Strugnell's allotment was published in 1994.
Change of direction As early as 1956 Allegro held controversial views regarding the content of the scrolls, stating in a letter to de Vaux, "It's a pity that you and your friends cannot conceive of anything written about Christianity without trying to grind some ecclesiastical or non-ecclesiastical axe." The bulk of his work on the Dead Sea Scrolls was done by 1960 and he was at odds with his scrolls colleagues. When a conflict broke out with H.H. Rowley concerning Allegro's interpretation of the scrolls, Allegro, on the invitation of
F. F. Bruce, moved from the Department of Near East Studies in the Faculty of Arts at Manchester to the Faculty of Theology. Allegro further argued that the authors of the Christian gospels did not understand the Essene thought. When writing down the Gospels based on the stories they had heard, the evangelists confused the meaning of the scrolls. In this way, according to Allegro, the Christian tradition is based on a misunderstanding of the scrolls. He also argued that the story of Jesus was based on the crucifixion of the
Teacher of Righteousness in the scrolls. Mark Hall writes that Allegro suggested the
Dead Sea Scrolls all but proved that a historical Jesus never existed. Allegro argued that Jesus in the
Gospels was in fact a
code for a type of
hallucinogen, the
Amanita muscaria, and that Christianity was the product of an ancient "sex-and-mushroom" cult. Critical reaction was swift and harsh: fourteen British scholars (including Allegro's mentor at Oxford, Godfrey Driver) denounced it. Allegro's theory of a shamanistic cult as the origin of Christianity was criticised sharply by Welsh historian
Philip Jenkins who wrote that Allegro was an eccentric scholar who relied on texts that did not exist in quite the form he was citing them. Jenkins called the
Sacred Mushroom and the Cross "possibly the single most ludicrous book on Jesus scholarship by a qualified academic". Based on the reactions to the book, Allegro's publisher later apologized for issuing the book and Allegro was forced to resign his academic post. In November 2009
The Sacred Mushroom and the Cross was reprinted in a 40th anniversary edition with a 30-page addendum by
Carl Ruck of
Boston University.
Later career After the publication of
The Sacred Mushroom and the Cross in 1970 Allegro resigned his post at Manchester. He worked thereafter as an independent writer and broadcaster, continuing a public campaign for wider access to the Dead Sea Scrolls and for open debate on their significance. His subsequent books addressed biblical origins, religion, and science for a general audience, including
The End of a Road 1970,
The Chosen People 1971,
Lost Gods 1977, and
The Dead Sea Scrolls and the Christian Myth 1979. He later published
All Manner of Men 1982 and
Physician, Heal Thyself 1985. In
The Dead Sea Scrolls and the Christian Myth (1979), Allegro presented a maximalist Essene hypothesis for
Christian origins, arguing that the
historical Jesus of the
Gospels was a recasting of the
Teacher of Righteousness from the
Dead Sea Scrolls and that key
New Testament themes were prefigured in
Essene writings. The work used
pesharim as historically referential documents to reconstruct conflict under
Hasmonean rule, connecting the
Nahum Commentary to
Alexander Jannaeus's crucifixion of 800 opponents in 88 BCE and proposing that sectarian trauma and
messianic exegesis shaped later Christian mythmaking. Contemporary academic reviews were predominantly negative, with
Joseph A. Fitzmyer characterizing the work as relying on "many generalizations, strained etymologies, one-sided reading of evidence, and a patent desire to titillate," and later scholarly surveys noted that Allegro's model did not gain traction in mainstream Dead Sea Scrolls scholarship. Years later, Allegro continued this criticism in his essay
Keeping the Secrets of the Dead Sea Scrolls (1984). Allegro asserted that the
publication delays and incomplete release of the
Dead Sea Scrolls have been influenced by scholarly possessiveness and deliberate suppression of potentially controversial religious information. He argued that only 20 percent of the scrolls were published by 1984, attributing the delays primarily to the editors' reluctance to share their assigned texts until they fully exploited the material for personal academic advantage. Allegro further stressed that ecclesiastical authorities reacted defensively against interpretations that might diminish the perceived originality of
early Christianity, actively dismissing parallels between
Essene teachings and Christian narratives, such as possible links between
Jesus and the Essene
Teacher of Righteousness. He cited an instance where his colleagues explicitly distanced themselves from his own interpretation connecting an Essene text to historical crucifixion events. Allegro recounted his experience with the suppression of information regarding the
Copper Scroll, a document listing hidden temple treasures, which authorities initially withheld from the public by claiming its contents lacked historical relevance. In the early 1980s he lived on the Isle of Man, then returned to England. He remained outside formal academic employment, lectured and broadcast frequently, and continued to write until his death. ==Reception==
