Number, Harmony and the Measure of Heaven and Earth brings together six leading exponents in the fields of the Quadrivial Arts/Sciences. The Symposium programme balances the presentation of theoretical/philosophical visual talks including the sharing of current research/discoveries with hands on practical sessions. The integrative approach of the presenters mirrors the integrative nature of their work and research and promises to leave participants enthused and nourished - head, heart and hands.

Tea Break
Adam Tetlow - A Harmonious Universe: 

Explore the ancient science of harmonics with geometer Adam Tetlow and discover astonishing connections between the arts of number and the origins of human culture. Bringing together new research with the work of John Neal, John Michell, R.A.Schwaller de Lubicz and a cast of scientists and visionaries. This talk promises to radically deepen your perception of ancient humanities' understanding of sound, geometry, measure and the universe.

With monochord demonstrations and beautiful diagrams.





John Martineau - '(On 'Venus and Beauty' details tbc)

Jonathan Horning

The Rose Window as Cosmological Union of Heaven and Earth

(A Practical workshop with compass and straight edge)

Tom Bree - The Cosmos in Stone

A twelfth century Christian education involved the so-called Seven Liberal Arts. Four of these seven arts were concerned with number and together they were called the Quadrivium. They were arithmetic, musical ratios, geometry and cosmology. All four of these subjects inform the design of Wells Cathedral although this

particular talk will concentrate upon the cosmological aspect of the design.

Gothic Cathedrals are often looked upon symbolically as architectural images of the

Heavenly Jerusalem – (the Heavenly City described at the end of the final book of the Bible). So to

enter into such a cathedral is to ‘walk among the stars’. It is where God’s Will is

done ‘on Earth as it is in Heaven’ – a place in which ‘the Morning Star rises in your hearts’.

Modern cosmology is essentially a materialistic description of matter and its movements whereas medieval cosmology was a study by which the soul contemplated the eternal Reality of God – the ‘Divine Geometer’ – via the ordered Creation. In this sense God was equated with the artisan who employed the eternal

laws of mathematics and geometry to fashion the Cosmos.

This talk will look at the underlying geometric design of the ground plan of Wells Cathedral and the way in which it embodies a Jerusalem-centred cosmological symbolism that is still used today in the

symbolic layout of a Freemason lodge room.

Tom Bree

A Practical workshop with compass and straight-edge elucidating aspects arising from Tom's

proceeding Cosmos in Stone talk



Adam Tetlow

Geometry and Earth Measure

Using compass and ruler this short workshop will explore how a precise model of the earth can be drawn

from the harmonic relationships generated by the square.

Hartmut Warm - Harmony of the Spheres 

Modern astronomical procedures have enabled Hartmut Warm to discover astounding musical and geometrical structures and wonderfully aesthetic movement figures in our solar system. The ancient concept of a ‘harmony of the spheres‘ is confirmed in a new and fascinating way. The cosmos breathes mysteriously in geometrical structures. These structures are similar to archetypal forms in other realms of nature. The results of his work are represented with the aid of computer projections that provide a remarkable experience not only for astronomers but for anyone interested. Hartmut guides our understanding of the meaningful order in our solar-system to almost dizzying heights.

About the contributors

Tom Bree

Tom Bree is a geometer-artist, teacher and writer. He is a member of the cathedral congregation and lives in Wells with his wife and two young children. Tom teaches geometry and its accompanying philosophy at The Prince’s School of Traditional Arts in London as well as for various other educational organisations around the country. He has been a friend and contributor to SacredArtofGeometry since its inception in 2015. For the past seven years Tom has been researching the underlying design of Wells cathedral. He is currently writing a book on the subject.


Daniel Docherty

Daniel Docherty studied sacred and traditional arts and geometry with

Keith Critchlow and Paul Marchant. He received his MA from

The Prince's School of Traditional Arts, London, in 2004 and has subsequently taught and researched extensively in these disciplines in the UK and Worldwide. In 2015 he co-founded SacredAtofGeometry and SAOG Studios in East Sussex, UK with fellow Artist/Geometer Kira Orsak.


Jonathan Horning 

Jonathan Horning has taught geometry and workshop skills at The Prince's School of Traditional Arts for over 20 years. He is an experienced carpenter and joiner and is the author of Simple Shelters: tents, tipis, yurts, domes and other ancient homes (Wooden Books). He lives in Devon, UK with his wife Amanda Critchlow Horning


Adam Tetlow

Adam Tetlow is an artist, geometer and writer. A former student of Keith Critchlow, Adam is author of Celtic Pattern, co-author of Sacred Number (as Miranda Lundy) and contributor to Quadrivium, Designa and Trivium, all published by Wooden Books. His forthcoming book Ancient Metrology: Harmonic Number Science, is the summation of four years of research in close consultation with John Neal. Adam teaches geometry courses with the PSTA, his website is


John Martineau  

John Martineau is publisher and editor of the international award-winning Wooden Books pocket liberal arts series, which has been translated into 20 languages worldwide.  Also the author of A LITTLE BOOK OF COINCIDENCE IN THE SOLAR SYSTEM, his primary hobby is collecting solutions to the Cosmological Anthropic Principle.


Hartmut Warm

Hartmut Warm was born in 1956, is a civil engineer and independent researcher in astronomy, geometry, the history of harmonics and musical aesthetics. He has taught, lectured and published widely on these and other subjects, and in particular on his discoveries relating to the solar system and its inherent order. His book Signature of the Celestial Spheres was published by Sophia Press/Rudolf Steiner Press in 2010. He lives in Hamburg, Germany.
