Dis-moi dix mots is a campaign to raise awareness of the French language, inviting everyone to play and express themselves in artistic and literary form. On the list of ten words, I chose to work around the word “shell”. This word characterizes a protective, hard and limestone shell of eggs and most molluscs. But it also defines a protective envelope that man creates in order to protect his personality. That’s the part I chose to work on. Indeed, I made the choice to work on the matter, that of different shells to raise this idea of envelope, history, fossilisation and footprint.
