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 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
  • share our work with and encourage research via the Quatuor Coronati 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

We hosted more than 200 visitors at our ‘1717 and All That’ 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 full set of papers will be made available via the next issue of the Transactions – AQC 131. Videos of the principal talks have been posted to YouTube and can be accessed here:

Papers from a number of speakers from the floor and part of the Q&A session can be viewed here:

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

Our 2018 conference will be held from 14-16 September 2018 at the magnificent George Washington Masonic National Memorial in Alexandria, VA, a unique and wonderful venue just over the river from Washington DC. The focus is on 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.

The Conference is an outstanding event for those who wish to gain a better understanding of 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 will also participate in a debate and discussion regarding the inception of the first Grand Lodge – 1717 vs.1721 – at which Susan Sommers and Ric Berman will once again debate the contrasting positions; attend a Universal lodge and talk explaining the Masonic symbolism in DC; and have the option to tour the George Washington Masonic National Memorial and Washington DC, and join us for a convivial Saturday evening dinner.
