Who was the Greek geographer known for his work during 64 CE to 21 AD?

The Greek geographer known for his work during the period of 64 CE to 21 AD is Strabo. He is best known for his monumental work, "Geographica," which provided a comprehensive description of the world as it was known in his time, including regions, peoples, and cultures across Europe, Asia, and Africa. Strabo's writings were significant because they synthesized earlier geographical knowledge and added his observations, providing a critical link in the development of geographical thought.

Strabo's contributions also included discussions on philosophical and historical contexts that influenced geography, making his work a valuable resource for understanding the geography of the ancient world. His perspectives reflect the blend of scientific observation with practical insights about the journeys and experiences he encountered, which were integral to the geography of his time.

Though other figures like Herodotus, Ptolemy, and Hecataeus made significant contributions to geography, they did not align with the specific timeframe of 64 CE to 21 AD as closely as Strabo did, highlighting his unique place in the history of geographical thought.
