composed Modotti's epitaph, part of which can also be found on her tombstone, which also includes a relief portrait of Modotti by engraver Leopoldo Méndez: Pure your gentle name, pure your fragile life, bees, shadows, fire, snow, silence and foam, combined with steel and wire and pollen to make up your firm and delicate being. Murals by Diego Rivera that include Modotti The Abundant Earth, The National Agricultural School, Chapingo, 1926 In 1926, Diego Rivera's wife Lupe Marín asserted that her separation from her husband was caused by his affair with Modotti, which had arisen from Modotti's nude modeling for him for the murals as the Abundant Earth at the National Agricultural School in Chapingo, near Texcoco [1926–27].

The final rift between Modotti on the one hand and Rivera and Kahlo on the other, less than a month later, appears to have been political rather than personal. Modotti supported Rivera's expulsion from the Communist Party. Modotti's internationalism, and her belief that this was
