Gramsci wrote nothing about Russia despite living there for eighteen months

Evidence

Remarkably little is known about this period in his life. One of the most surprising features of his published writings is the absence of any reflections on, or even descriptions of, Russia as he knew it in the eighteen months he spent there at what was a crucial period in the history of the revolution. — Antonio Gramsci, Selections from the Prison Notebooks, 143

• QUESTION: Why did Gramsci produce so little reflection on Moscow even as his theoretical project matured? Worth chasing for what it implies about his intellectual method.
