Nico's lyrics have been described as "mythological and surrealist". According to "Spin", "for lyrical inspiration, Nico looked to the Romantic poets and peyote, passions shared with Jim Morrison." Stephen Davis wrote that the album's lyrics stem from the collaboration between Nico and Morrison, and his influence can be seen in song titles such as "Lawn of Dawns", "Frozen Warnings" and "Evening of Light". Morrison offered Nico a model for her writings by showing her how he worked on his poems, indicated by her use of internal rhymes. According to Peter Hogan, some of her lyrics "show a marked debt to Sylvia Plath and to William Blake" and a search for artistic legitimacy. Other critics have found Nico's lyrics to be intriguing. For example, Richie Unterberger wrote: "Nico intones lyrics that don't quite express specific feelings but convey a state of uneasy restlessness." They have also been described as "stark symbolist" and "metaphysical".
