The second volume of Herodotus famous histories details further conflicts between Macedonia, Sparta, Greece and Persia, including many of the great naval battles of the era.

In contrast to the first volume, the later books of Herodotus' Histories contain more detail on the aristocracies and rulers of each nation. Military matters at land and sea are discussed, with supreme commanders such as Alexander I of Macedon and Xerxes of Greece receiving scrutiny as to their strategic planning and behaviours.

Together with portions deemed factual and accurate are juxtapositions of Greek mythology upon the text. The famous passage concerning the rescue of the Delphic Oracle from an invading Persian army by supernatural forces is one example of myth in an otherwise historically reliable work.

Over his lifetime, Herodotus personally travelled around most of the ancient world. His expeditions to Egypt and Persia yielded discoveries significant to history, whereby local sources and libraries were consulted to better the comprehensive accuracy of his writings.

At the time of his original writing, the Persian Empire controlled many of the territories which Herodotus toured. Given the sprawling nature of this Empire, Herodotus is occupied with comparing the various cultural traditions and peoples within and outside its extent. Territories such as Scythia, and various smaller tribal groups, likewise fall within the author's sphere of examination.

Many of the methods Herodotus employed during his travels, such as explaining specific phenomena, buildings and conflicts with cited evidence, would influence future historians greatly. Although not all of Herodotus sources were reliable, the fact he recorded his histories during antiquity confer great value upon his work.

As well as his sources, Herodotus would personally observe the differing customs and behaviours of the peoples he walked among. Many of the culturally ingrained practices were considered strange, with Middle Eastern and North African traditions contrasting markedly with those of Greece and Europe.

Although much of what Herodotus wrote has been superseded by the discoveries and historic researches of later epochs, his work remains widely consulted by scholars and historians to this day. Generally praised by historians, Herodotus has since the Roman era held the title "The Father of History."
