Bonhams is delighted to present this superlative group of Earthworks by Grigorian from the family estate. The present examples are the most monumental, exquisitely rendered, and technically complex examples of his signature Earthworks, the present grouping provides a comprehensive and compelling account of the mature phase of Grigorian's oeuvre.

The Earthworks were inspired by the use of materials and forms that went beyond the conventional means of art-making. Compared to the Western Land Artists, who similarly created compositions through the handling of earth itself, Grigorian predated this movement by a decade.

These works are mostly in a square or rectangular format, which became something of a signature for Grigorian. The square form was a representation of sacred geometry and harmonious proportions. The organic materials such as hay, straw, sand, soil and clay which he used to create his almost three-dimensional compositions were to be equally defining.

In experimenting with soil and mud, he believed he was rebuilding life and exploring the complex relationship between mankind and earth. The present work is reminiscent of the commonly held theory that the Earth and the other planets developed over millions of years out of particles and gas. The traces of a convergent movement towards the centre of the canvas evoke the image of the universe forming out of primordial dust - and the monochrome earthy surface impress upon the viewer the feeling of a distant aerial view from space. The textured surface and the play between light and shadow endow the painting with an even more dramatic effect, adding to its three-dimensionality.

In 1965, The Museum of Modern Art, New York acquired a work from Grigorian's Earthworks Series on the recommendation of Alfred H. Barr Jr., the legendary former director of the museum. A second work was then donated to the museum by Nelson Rockefeller in 1978. Further examples of Grigorian's works were recently acquired by the Metropolitan Museum of Art in New York and can also be found in the collections of Tehran's Museum of Contemporary Art and the National Gallery of Armenia in Yerevan.

Besides being a leading figure in avant-garde Iranian and Armenian art history, Grigorian was an artist, writer, gallerist, collector, pioneer and a teacher. From his Gallery Esthétique in 1950s Tehran, which provided a free exhibition space for younger artists, to his pioneering decision to organise the first national Tehran Biennial in 1958 (after he was awarded the honour of representing Iran in the 1956 Venice Biennial) Grigorian desired to make an impact on the development of art.

He was instrumental in the introduction and promotion of modern art in Iran in the 1950s and extensively promoted the works of Armenian artists in the United States in the 1980s. Despite travelling around the world, Grigorian chose to return to his ancestral home of Armenia for the remainder of his life and donated his complete collection to the Armenian government as a sign of his lifelong commitment to his nation.
