Lau's book has two main focuses. On the micro level, he looks at different sages. He looks at each sage's enactments and appearances in Talmudic stories, especially in relation to the historical context around them, in an attempt to capture the personality and philosophies of each sage. On the macro level, he chronologically moves through Jewish history in Israel during the second temple period, mainly focusing on the enactments of the Anshei Knesset HaGedola, the Hasmonean Dynasty, and the Roman rule until the destruction of the temple. The two focuses are often intertwined and help give context to the other.
Going into this book, I thought that Lau would strictly focus on the different sages and explain their philosophies and biographies. As someone who studies Talmud, I believe that giving identity to the different Rabbis and the motivation behind their opinions provides a deeper and more meaningful understanding of the Talmudic debates. However, I did not realize the amount of text that would be allocated towards Jewish history.
Generally, I think that Lau does a good job of combining academic and Tannaitic sources to a holistic view of each sage and historical context. I felt that sometimes his historical analysis could get a bit repetitive. I enjoyed that parts more where he offered his opinion of a certain sage or showed a certain philosophy that emerges from analyzing that sage's appearance in academic and Tannaitic literature. However, especially towards the end, the historical context came into the forefront and the sages of the time were just used to help understand the historical context, instead of vice-versa. However, this shift may be because there is little Tannaitic literature on sages of the pre-temple destruction era and few prominent personalities, and thus Lau had little to work with.
