Several political prisoners told me that, at night, when the prison fell silent, when, in Uncle Mahmoud’s words, “you could hear a pin drop or a grown man weep softly to himself,” they heard this man’s voice, steady and passionate, reciting poems. “He never ran out of them,” his nephew, who was in prison at the same time, told me. And I remember this man who never ran out of poems telling me once that “knowing a book by heart is like carrying a house inside your chest.”
