Query: Meticulously researched

Mary Renault did meticulous research for her story of Alexander the Great from birth to manhood. It is told from the viewpoint of another young man, employed by Alexander, who became his personal servant and close friend. The various happenings in Alexander's life are taken from recorded history, and fully filled out with descriptions of the culture and mores of the times. Most of the people mentioned were actual persons who interacted with Alexander, including his parents, who fought bitterly over his allegiance to each of them. I found it a fascinating history, and noted a stark comparison of times throughout the ages. Nothing changes.
