The Legend of the Quatuor Coronati

Quatuor Coronati is the world’s premier research lodge. Established in 1884 (and consecrated in 1886), the lodge’s founders wished to advance an evidence-based approach to study Masonic history and research the origins of Freemasonry. Their approach was intended to replace the more imaginative writings of earlier authors and was later referred to as the ‘authentic school’ of Masonic research.

Quatuor Coronati adopts the same principles today. We hold meetings incorporating lectures five times a year, most commonly at Freemasons’ Hall, Great Queen Street, London. Publish our lectures, other research papers and ‘notes & queries’ annually in Ars Quatuor Coronatorum – ‘AQC’, the Transactions of the Lodge, which is distributed internationally. Arrange conferences and symposia on different aspects of Freemasonry and Masonic research. And seek to share our work with and encourage research via the Correspondence Circle – ‘QCCC’.

The Correspondence Circle was inaugurated in 1887 and is an international community. Whether you are based in North or South America, the UK, Europe, Africa, Asia or Australasia, we would be delighted if you would like to become involved with Quatuor Coronati. The first step is to join QCCC which is open to everyone interested in Masonic research or historical research more broadly.

Major Events in 2018

14-16 September 2018: QC Conference – ‘Freemasons in the Transatlantic World’

The magnificent George Washington Masonic National Memorial in Alexandria, VA, a unique and wonderful building just over the river from Washington DC, is the venue for our Conference from 14-16 September 2018. The focus is on the transatlantic influences in the first century of freemasonry in America and the Caribbean. QCCC members benefit from preferential booking and discounted entry. Please click HERE to see the Conference Brochure or download our QC Conference Flyer.

The Conference is a ‘must-go’ event for those who wish to understand the beginnings of American freemasonry, network with QC/QCCC members including Brent Morris, Arturo de Hoyos, Andreas Önnerfors, James Campbell, Adam Kendall and Ric Berman, and hear from and debate with world-class speakers. Attendees can also participate in a discussion regarding the date of the first Grand Lodge – 1717 vs.1721 – at which Susan Sommers and Ric Berman will debate their contrasting positions. The Conference features a ‘Universal Lodge’ and a talk explaining the Masonic symbolism in DC, and delegates have the option to tour the Memorial and Washington, and to attend a convivial dinner on Saturday evening.

‘1717 & All That’ – Symposium

We hosted more than 200 visitors at our Symposium at FMH in London on 15 February, with short papers presented from the floor in addition to the four main speakers: Professors Andrew Prescott & Susan Sommers, arguing that the first Grand Lodge was not formed in 1717 but 1721; and John Hamill & Dr Ric Berman, contending the reverse. The papers will be made available in the next issue of QC’s Transactions – AQC 131. Videos of the principal talks have been posted to YouTube and can be accessed here:

Andrew Prescott   Susan Sommers  Ric Berman   John Hamill

The papers delivered on the day and received subsequently will be published in AQC 131, which will be available from December and mailed to all members of the Correspondence Circle.
