Jardin de l'Alchemiste in Eygaliéres in the Bouches-du-Rhone department of France, is situated next to the 16th century Mas de la Brune, the historic residence of Pierre Isnard, a steward to the Duke de Guise. Isnard evidently harboured a medieval fascination with magic and as a consequence incorporated certain alchemical symbols into the architecture of the mansion. This provenance inspired the current owners Marie and Alain de Larouziére, and provided them with the conceptual framework for the garden which they made in 1997. Spurning traditional ideas of arrangement in favour of creating a metaphorical journey representing the alchemical quest for the philosophers stone, the legendary substance thought to be capable of turning lead into gold, the garden is certainly unique.

Intended as a philosophical essay on the process of enlightenment, evoked through the spatial layout of the garden and it's horticultural arrangement, the narrative drive of the garden is provided by the historical associations of local plants, their forms and colours. Numerology plays a role in the design layout (the numbers 5, 7, 9, 11, 22, 33 having a alchemical importance), whilst reference is implied to astronomy (Saturn, Mercury, the moon and the sun). As such the garden suggests a certain element of theme park whimsy, yet the planting manages to counterbalance any such tendencies with it's imaginative array of Med-friendly plants which form a kind of hermetic vocabulary enunciating the ideas the garden presents.

The design of the garden by Arnaud Mauriéres and Eric Ossart, the French/Moroccan duo responsible for creating a hybrid design style fusing the Modernism of Luis Barragan with traditional aspects of Islamic paradise gardens, is certainly not typical of their work but rather reflects a more arts based approach to gardens which nods to their involvement in the early years of the International Festival of Gardens at Chaumont-sur-Loire.

The garden is entered though an Eleagnus maze formed from the Hebrew word 'Bereshift', the first word in the Torah, meaning appropriately enough 'in the beginning'. This leads through a wooded area of cypress, oak and pine into an ethnobotanic garden which explores the historic uses of local herbs and plants in medicine and magic, with an emphasis placed upon the relationships between place, belief and tradition. The planting palette incorporates such usual suspects as sage, lavender, nettle and St John's Wort, alongside walnut, olive, almond and apple trees, as well as roses.

The formal aspects of the layout of this part of the garden bear certain recognisable Mauriéres and Ossart trademarks such as the use of square geometry, with four large and eight small beds, and a central linear rill. This neatly breaks up the space into distinct areas whilst a bi-secting arbour covered with twenty-two types of vine, provides an effective visual screen and a practical place for repose and reflection.
From this area the visitor progresses through what are described as the three Works - the Black, the White and the Red, symbolising periods of personal development, and distinctly differentiated from each other through the use of colour, light and enclosure.

The Work in Black represents the individuals birth and physical growth and utilises a reduced palette of black and green elements. Slate pathways lead between tall beech hedges creating a series of alleyways, the first empty, the second and third containing eleven pots. The Aeonium arboreum in the third passage providing striking sculptural counterpoints to the rhythmic motion through the space.

The dense, dark and slightly claustrophobic atmosphere of these spaces is dramatically contrasted with the Work in White, an enclosure filled with Miscanthus sinesis 'Variegatus' and Rosa 'Iceberg' and 'Snow Fairy', representing intellectual and emotional development.
A circular portal in the hedging projects the visitor in to the Work in Red, the garden of the soul and spiritual enlightenment planted with red roses. A circle of pomegranate trees frame a pond in the form of a six pointed star with a singular central fountain, representing the philosopher's stone, and the culmination of the journey from darkness to light, from the base to the precious.

Given that the garden is defined by the ideas it attempts to articulate, it undoubtedly requires a certain leap of faith to appreciate it's intent. Whilst certain areas provide habitable spaces, it is definitely less a place to linger than a performance in which each visitor is the central actor. However the deft design work of Mauriéres and Ossart manages to balance the conceptual with the corporeal, and succeeds in producing an individual and quirky work of artifice.
