Leonie Siri MacMillan is an interdisciplinary artist working across sculpture, drawing and film. She is a nomad at heart, drawn to the ocean and bodies of water.  Her practice investigates mythology as a way of understanding complex emotional and environmental experiences.

Presently she is developing a technique of drawing with seawater and ink, that allows the pigments to move freely until the seawater evaporates.  The drawings help her to discover shapes for ceramic sculptures that form the basis of an imaginary world inspired by Orcadian legends.  She is in the process of inventing a new mythology, led by the sea goddess Mitherspher.  It's a world that involves fin maidens that live under the magical island of Eynhallow, while subterranean creatures lurk in the shadows.  The goddess’s mission is to heal failing ocean currents and sea mammals.  Within this new work, she hopes to demonstrate the inherent strength of Women combining with the preservation and restoration of ocean ecologies, in response to climate change.

Her ceramic sculpture is made with various stoneware clays, high-fired and decorated with coloured slips, melted glass, circular markings and sometimes photographic images.  Her glazes and shapes are informed by the abstract interpretation of her invented mythology, drawn with seawater ink on Fabriano paper.
