One of Mucha’s best Czech posters, printed by the firm of V. Neubert in the Smichov quarter of Prague, was for Princezna Hyacinta, a fairy-tale ballet and pantomime with music by Oskar Nedbal and libretto by Ladislav Novák. The portrait of the popular actress Andula Sedlácková as the princess dominates the poster. The plot develops as a dream of a village blacksmith who falls asleep after digging for a buried treasure. In his dreams he becomes lord of a castle, and his daughter Hanicka becomes the Princess Hyacinth. Of her three suitors, one is a sorcerer who abducts her to his underground palace, but she is rescued by a poor knight who looks like her real-life lover. Mucha used the motif of the hyacinth throughout the entire design, from embroideries to silver jewelry, and for an elaborate circle sparkling against the mossy green background. The portrait of the actress is seen against a sky full of stars and encircled with images from the dream: the blacksmith’s tools, a gold crown, hearts speared by arrows of love, the sorcerer’s alchemical vessels, and his strange monsters.”
