For me personally, books on history are very important because it allows me to gain new information and learn more about the emperors depicted on coins. I also like to take a critical look at antique sources, to ask questions about whether the information provided is correct. But now to the point. 3.Herodian, history of the Roman empire from the death of Marcus Aurelius to the reign of Gordian III This was one of the first ancient sources that I read. The book is interesting because it describes the impetus for the crisis of the third century. The writer has his limitations, but describes well what happened in the period in Rome. The author is also fairly neutral. Although the style is not good, the author can describe a lot of information in a short time frame. 2.Tacitus Agricola A short book by Tacitus about the career of his father-in-law Agricola. The book continues with an occasional highlight such as the battle of Mon Graupius. In the end, the emotion bursts and the hatred of Domitian becomes clear, because he did not grant Agricola glory and probably had him poisoned. I think this book is great because it is not too long-winded, And Tacitus writes some very personal pieces. 1. Tacitus Histories The histories of Tacitus are my number one. Originally this book described the beginning of 69 to the death of Domitian. Unfortunately, only four of the total of fourteen books are left. The remaining books describe the year of the four emperors and the rise of the emperor Vespasian. What I love about this book is that Tacitus has the gift of giving excellent character descriptions in short sentences. His book is not only historically interesting, it is also strong stylistically. To make it legal a coin from the time period of the Histories. Vespasian 69-79 AR Denarius struck January-June 70 3,46g/18mm IMP CAESAR VESPASIANVS AVG laureate head right.
