While it is undeniable that Herodotus makes some mistakes in his work, his Histories are generally reliable and scholarly studies in all disciplines concerning his work (from archaeology to ethnology and more) have continued to substantiate all of his most important observations. Herodotus identifies himself in the prologue to his work as a native of Halicarnassus (on the south-west coast of Asia Minor, modern Turkey) and this is accepted as his birthplace even though Aristotle and the Suda claim he was a native of Thurii. This discrepancy is generally understood as a mistake made in an ancient source (possibly a translation of Herodotus' work) as Herodotus may have lived on the island of Thurii but had not been born there. He traveled widely in Egypt, Africa and Asia Minor and wrote down his experiences and observations, providing later generations with detailed accounts of important historical events (such as the Battle of Marathon in 490 BCE and Thermopylae and Salamis in 480 BCE) everyday life in Greece, in Egypt, in Asia Minor and on The Seven Wonders of the Ancient world. His description of The Walls of Babylon as among these wonders is an example of why his work has often been criticized.
