What kind of historical writings found in classical phase and hellenistic phase respectively during the Greco-Roman historiography?

During the classical phase of Greco-Roman historiography, which roughly spans from the 5th century BCE to the 4th century BCE, the predominant form of historical writing was the "logographic" tradition. Logographers were historians who wrote in a concise and factual manner, focusing on specific events or topics. They aimed to provide a chronological account of events, often focusing on political and military history. Some notable logographers from this period include Herodotus, Thucydides, and Xenophon.

In the Hellenistic phase of Greco-Roman historiography, which began in the 4th century BCE and continued until the 2nd century BCE, there was a shift towards more comprehensive and philosophical approaches to history. This period saw the rise of "universal history" or "world history," which aimed to provide a broader understanding of the world and its civilizations. Historians during this phase often incorporated elements of geography, ethnography, and cultural analysis into their works. Prominent historians from this period include Polybius, Diodorus Siculus, and Appian.
