Nicomedia of Arrian: - "Arrian of Nicomedia (c. 86 - c. 160 AD) was a Greek historian, philosopher, and statesman. He was born in Nicomedia, a city in Bithynia (present-day Izmit, Turkey) and later moved to Athens to study philosophy under the tutelage of the philosopher Epictetus. Arrian began his career in politics as a senator under the Roman Emperor Hadrian and later served as the governor of Cappadocia, a province in eastern Turkey. During his time in public office, he gained a reputation as a just and fair administrator. Arrian's historical works were highly regarded by later historians and scholars for their accuracy and attention to detail. He was known for his meticulous research and his ability to synthesize disparate sources into a cohesive narrative. He also had a keen interest in military strategy and tactics, which is evident in his descriptions of Alexander's campaigns. Arrian's legacy as a historian and philosopher has endured to the present day. His works have been widely translated and studied, and his influence can be seen in the writings of later historians and philosophers, including Plutarch and Marcus Aurelius."
