Odilon Redon's 1878 drawing "Eye-Balloon" (Œil-ballon) exemplifies his fascination with the surreal and symbolic. Executed in charcoal and chalk on colored paper, the artwork depicts a hot-air balloon in the form of a human eye ascending above a marshy landscape, with a severed head resting on a plate beneath it. This imagery reflects Redon's interest in exploring the boundaries between reality and imagination, inviting viewers to ponder the enigmatic symbolism of the floating eye.
