[2] The indelible impressions of her childhood – the glowing, shining power of the sun, the close relation with animals, with the always fragrant vegetation, and last but not least with her mother – had left Cuz with a longing that demanded expression.
Scenes and colors of her native land were deeply imbedded in her psyche and appeared to her in dreams and visions, which she began to express in her art in 1950.
Cuz created scenes in which motifs from the world of myths and legends from everyday Mayan life dominate.
Her interest in world religions, especially in the Maya cosmovision and Buddhism, is particularly evident in her later works, which deal principally with spiritually inspired subjects.
In 1968 Cuz' and Georg Schäfer's book In the Kingdom of Mescal was published, an illustrated fairy tale for adults based on indigenous Guatemalan folklore.
