[Historike te kai geographike ereuna peri tou pyrenos tou archaiou Makedonikou vasileiou

This is a short essay written in 1888 by Παναγιώτης Γεωργίου Παπακωνσταντίνου / Panagiotes Georgiou Papakonstantinou, about the geography and ancient history of Ημαθία / Imathia, (then part of Othoman Empire, today part of Greece). It is the greek original text of a work submitted to the University of Leipzig, Germany. There are no biographical data about the author. He dedicated this book to his uncle Neophytos, the greek-orthodox bishop of Pelagonia / Πελαγονία (modern Пелагонија, FYROM).

Papakonstantinou, born an othoman citizen describes himself simply as "ethnic greek" ("Μακεδόνος" as a title under is name in first page). His thesis is that the core of the ancient greek kingdom of Μακεδονία / Macedonia was the area of Imathia, and gives a detailed description of the geography and ancient history, with references to ancient authors and modern scholars.

It is written an an archaic and artificial form of greek. This can be a problem for someone with elementary knowlege of modern greek.
