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 or ‘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.

The QC Correspondence Circle 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 in the research activities of Quatuor Coronati. The first step is to join the Correspondence Circle, which is open to anyone interested in Masonic research or historical research more broadly.

QC’s Conference in the USA: 14 – 16 September 2018

We are holding a conference and symposium at the magnificent George Washington Masonic National Memorial in Alexandria, VA, a wonderful venue just over the river from Washington DC. The Conference focuses on the first century of freemasonry in America and the Caribbean. QCCC members obtain discounted entry and early-bird tickets are available now. This is an outstanding event for those who wish to gain a greater understanding of the beginnings of American freemasonry and network with those having similar interests. Needless to say, we have lined up a number of world-class speakers for the event. Attendees will also see exclusive highlights of the Tercentenary Celebration of the foundation of the first Grand Lodge; attend a universal lodge in DC that will include a talk on the capitol’s masonic symbolism; and have the opportunity to tour the GWMNM and Washington DC. The full Conference Program can be obtained here and early-bird tickets should be booked now.

Other New Developments…

Thursday, 14 September 2017: QC hosts the 2017 Prestonian Lecture – ‘The Grand Design’.

Thursday, 15 February 2018: ‘1717 And All That’. Another exceptional event for your diary: QC is hosting a Symposium to discuss the differing views regarding the foundation of the Grand Lodge of London & Westminster – later the Grand Lodge of England – and the nature of the evidence for and against the conventional date of its emergence. Professors Andrew Prescott & Susan Sommers will argue the case that the Grand Lodge was not formed in 1717 but 1721, and John Hamill & Dr Ric Berman will contend that the traditional date remains correct. Attendees who wish to speak from the floor are invited to email the chairman of the Symposium, Emeritus Professor Aubrey Newman, at The Symposium is open to all, masons and non-masons alike; we plan to start at 3.30 pm in LR9, Freemasons’ Hall, Great Queen Street, London. The evening will conclude with a buffet supper.  A booking form will be available nearer the date. See the full QC programme for the year here.

Ric Berman’s latest book Espionage, Diplomacy & the Lodge tells the story of Charles Delafaye, a leading freemason, and the connections between eighteenth-century freemasonry and the British secret service. It is available through Lewis Masonic and via Amazon in the USUK and elsewhere.
