Please book via Eventbrite,

When you book, please also email us on to let us know if you wish to take part in the lunchtime drawing workshop on Saturday 21st (limited places), and to give us your 1st and 2nd choices for the workshops on Sunday 22nd.

We advise early booking as spaces are limited in all the workshops. Nevertheless they all offer the possibility of truly sacred, mathematical experiences so if you don’t get your 1st choice, there will be another path for you to explore.

You can, of course, tell us your full choice for the Sunday – how fully we can fulfil this, will depend how early you book. You are welcome also to introduce yourself to us in your email. If we are oversubscribed, there may be last minute cancellations and we may be able to offer you a place.


Lectures, workshops, performances

If you would love to live the sacred in your everyday, please come along. If you are asking, What is really real? What is really important?, please come along.

Sacred mathematics can lead you to the Divine. This experience of living, qualitative mathematics was at the heart of the Pythagorean teaching in ancient Greece. Over the centuries the other, technical, quantitative aspect was increasingly developed and the spiritual aspect was unfortunately neglected.

The 7 liberal arts also have their roots in ancient Greek times. They comprise the trivium, logic, grammar and rhetoric; and the quadrivium, arithmetic, geometry, music and astronomy.

This festival is an introduction to these approaches to deepening our reality, vitally needed to help us come through the multiple problems of our modern world.

These ancient knowings hold keys for us all, in the maelstrom of the modern world, to live fully as responsible, incarnate spiritual beings.

On Saturday you can hear from eminent experts, introducing you to some of these vital ideas.

Then, delight in Sacred Mathematics in Music, an exqusite piano recital by the renowned pianist, Douglas Finch, with music by Bach, Chopin and others. You will also be able to offer suggestions for pieces of sacred music which Douglas will improvise around.

On Sunday you have the opportunity to engage practically with these sacred arts through movement, voice, drawing, needlework and scientific experimentation.

In the plenary sessions we will invite not only questions and comments but also suggestions as to ways of continuing this work together.

See below for more details of the ramme and the presenters.

Speakers’ books and general titles will be available.

There are many cafes and restaurants very near Steiner House. Lunches might also be possible in Steiner House: please email us to register interest by 11th October latest. Society members 10% discount in Steiner House.

Good wishes and blessings,

Nicola Graves-Gregory, Sylvia Francke,

The festival is an initiative of the Mathematical, Astronomical and Science Group of the Anthroposophical Society GB.

A little more about some of the workshops


: There is an elegant geometrical way of drawing the 8 year cycles of Venus around the earth. We shall do the drawing and in the process learn about the harmonies in space and time which the drawing represents. Alongside our practical geometry we shall discuss the cultural and spiritual aspects of this interplanetary relationship.

Bothmer gymnastics

will help you to develop more awareness of the mathematical principles in all human movement, for example, the 3 spatial planes, and 6 directions, all of which are qualitatively different. This can bring more consciousness of movement, along with ease and joy to all your activities. Count Fritz von Bothmer developed the basic exercises in the 1920's from insights of Rudolf Steiner.

Cecchetti’s Method

of ballet will enable you to experience the natural movements of your body as sacred mathematics. Cecchetti (1850 -1928) understood that classical ballet, which originated in the court of Louis XIV, le Roi Soleil, was a movement of the mind, that manifested itself through the pairing of music and gesture, beginning with the 5 basic positions and 6 physical principles of the human body. In the workshop you will explore his ‘Days of the Week’ exercises, beginning with Monday’s aplomb, vertical standing, and completing with Saturday’s, ballon, bouncing (sacred and fun!)

Chi Gong:

Chi = Life Energy   Gong = Way, Method, Work. Chi Gong consists of methods that help you develop awareness of the chi, whilst circulating and strengthening it.


means ‘harmonious movement’ in Greek. It began in the 1920’s from suggestions of Rudolf Steiner about the deeper meanings in dance and movement. In this practice you can become aware of how the physical body, the soul and the spirit, unite with the space around to connect us not only with others, but also with the movement of the cosmos.

As human beings we communicate with others through the sounds we speak and the gestures we make. Both of these, sound and gesture, come from within and move outward through space as we speak and move. In Eurythmy you can discover how to unite the two to open yourself to a new understanding of your inner being in relationship to the world around you.

The Vesica Piscis

is an ancient, spiritual symbol. It is the intersection of 2 equal circles where the centre of each lies on the circumference of the other. It is on the Chalice Well at Glastonbury, and in Chartres cathedral. It is a symbol of manifestation, meeting and birth. In the workshop you will experience, through simple movement exercises, different qualities of meeting, meeting others, meeting the Self.
