Creating an elegant and unexpected harmony around a quartet of mandarin, violet, immortelle, and suede, Marc-Antoine Barrois and Quentin Bisch have dreamt of this new planet: Ganymede. The rocky satellite of Jupiter discovered in 1610 by Galileo is both luminous and covered with salt-water oceans. It acquired its name from Greek mythology: a young man, Ganymede, was kidnapped by gods who had been so enthralled by his beauty that he was offered immortality.
