The Guide to Famous Men of Greece is an optional supplement for the book. It includes, for each lesson, a vocabulary list and several discussion questions designed to bring out the key points of each life through a Christian (biblical) perspective. The discussion questions are excellent narration starters and really do help bring out the theme that "individual people and their actions have a significant effect on history". There are some ideas for simple hands-on projects (the first lesson involves making a salt relief map of the country in question, to get an idea of how geographical circumstances affect history). There are also suggestions for supplementary reading. I must say their book choices are quite wonderful and that all the books we acquired on Greenleaf's recommendation for ancient history have been treasures. There is also a timeline at the back which is helpful in unifying the various biographies.
