 Featured alongside the anachronism in The Battle of Alexander at Issus is a genuine lack of historicity. Altdorfer demonstrates minimal hesitance in neglecting the painting's historical integrity for the sake of its heroic style, in spite of the pains he took to research the battle. That the Persian army was up to twice the size of the Macedonian army is not clear, and the relative positioning of the soldiers as reported by ancient sources has been disregarded. According to art critic Rose-Marie Hagen, "The artist was faithful to the historical truth only when it suited him, when historical facts were compatible with the demands of his composition." Hagen also notes the historically baseless inclusion of women on the battlefield, attributing it to Altdorfer's "passion for invention" and saying they "look like German courtly ladies, dressed for a hunting party" in their feathered toques.
