Artistic and educational project as part of the artistic and cultural education course, led by the calligrapher artist Yves Dimier with a class of 5th and their teachers: French Mrs Clément and plastic arts Mr Boubred. The project aimed to introduce oriental calligraphy, with a strong environmental content, centered on the plant heritage of Pichat Park. Trees as living models: observation, feeling, interpretation. Technique "in one stroke" following the oriental philosophy. With the haikus imagined in parallel by the students, we will be in the presence of a complete project, using sight, hearing, touch... according to the theme 2024. And the works will be visible in nature, where they have their source.
