Aristobulus of Cassandreia

Aristobulus of Cassandreia, born around three hundred seventy-five BC, was a prominent Greek historian and military engineer. He hailed from Cassandreia, likely descending from a Phocian lineage. His close association with Alexander the Great marked a significant chapter in his life, as he accompanied the legendary conqueror on various military campaigns.

Throughout his time with Alexander, Aristobulus showcased his talents not only as a historian but also as an architect and military engineer. His expertise earned him the trust of the king, leading to his involvement in significant projects, including the repair of the tomb of Cyrus the Great in Pasargadae.

Aristobulus is best known for his geographical and ethnological writings, which, although surviving only in fragments and quotations by later authors, have been influential in historical discourse. His work served as a vital resource for historians like Arrian and was referenced by Plutarch, highlighting the lasting impact of his observations and insights.
