Some years ago I read Gorki's autobiographical trilogy (My Childhood, My Apprenticeship and My Universities) and greatly enjoyed all three volumes, being especially impressed by his lack of sentimentality and ability to make you feel that you're right there with him. Sometime later, I tried reading his novel 'Mother', but found that it did not have the same impact and I didn't finish it (I subsequently learned that Gorki himself considered that book a failure). Anyway, looking for more autobiographical stuff from Gorki, I found this.
The title's a little misleading as the book is really a series of portraits of Russian eccentrics that Gorky had known. Some are harmless oddballs, but a couple are scary psychopaths, and almost all have a mania for religion. The book also includes valuable portraits of Tolstoy and Chekhov. I particularly appreciate how Gorki never tells you what to think, leaving it to the reader to draw their own conclusions. From beginning to end, it's a fascinating trip back to a time and place in which people's thoughts and actions were heavily influenced by Christianity (often a distorted view of it).
