In 1968 Cima met the poet Eugenio Montale, by then in his early 70s, and became his last muse. She helped him organize the Posthumous Diary, a series of poems which were intended for publication after his death as a game against his critics. Though most critics today believe the poems are authentic, some accused Cima of writing the poems herself out of conversations with Montale, while others even believed she had forged them outright.
