To one not familiar w with the Russian language the accessible data relative to the external life of Leo Nikolaevich Tolstoi, the author of this book, are, to say the least, not voluminous. His name does not appear in that heterogeneous record of celebrities known as The Men of the Time, nor is it to be found in M. Vapereaus comprehensive Dictionnaire des Contemporains. And yet Count Leo Tolstoi is acknowledged by competent critics to be a man of extraordinary genius, who, certainly in one instance, has produced a masterpiece of literature which will continue to rank with the great artistic productions of this age.
