In 2004, Charles Avery embarked upon his evolving lifelong project, The Islanders, which describes in meticulous detail the inhabitants, flora and fauna of an imaginary island. In a constantly growing body of work (including drawing, sculpture and film), Avery explores and records in precise detail the customs, myths, religions and rituals of The Islanders. Four years into the process, in 2008, Avery was offered a solo exhibition at Parasol unit, which toured to the Scottish National Gallery of Modern Art, Edinburgh, and to Museum Boijmans Van Beuningen, Rotterdam. Tree No. 5 (from the Jadindagadendar) is a new and single work, jointly commissioned by Edinburgh Art Festival and Parasol unit, London.

Charles Avery (born 1973) is a Scottish artist from Oban. He currently lives and works in London. Since 2004 he has devoted his practice to the perpetual description of an imaginary island. Through drawings, sculptures and texts. Avery describes the topology, cosmology and inhabitants of this fictional territory, from the market of the main town Onomatopoeia to the Eternal Forest where an unknown beast called the Noumenon is held to reside. The project can be read as a meditation on some of the central themes of philosophy of art-making, and on the colonization and ownership of the world of ideas.
He is represented by Pilar Corrias Gallery in London and Grimm Gallery in Amsterdam."
