Query: Disapointment

This book is old, outdated and very naive in its approach to the subject matter.It is about time to see a new book about Sulla the dictator, a book which shall present all the recent research material to the modern reader.Amazon should warn the customers that this book is not a new creation but a re-print of an old book.On the other hand, although being useless for the student of ancient history, it is fluent and interesting.
