Depicted here is the hero of the story in his adventure to the moon. Originally an historical character: Karl Friedrich Hieronymus, baron of Münchhausen (1720-1797). As a Lieutenant and cavalry officer in a Russian regiment, he defeated the Turcs in 1716. Then he moved to Hanover, where he used to narrate his unbelievable adventures of war, hunting and travels. Rudolf Eric Raspe compiled these stories and embellished them. Thereafter several other adaptations were made adding both a satirical and poetic mood to the legend. The most recent, by director-producer Terry Gilliam,The Adventures of Baron Münchhausen, British film, 1989.
