Deceptive ancient texts were common enough that even Herodotus was dubbed Father of Lies

Evidence

Falsehood is probably as old as speech and certainly much older than writing. A significant proportion of ancient texts consists of lies, written with the intent to deceive as part of some propaganda effort. Accusations of falsehood in antiquity are not unusual. Even the great Greek historian, Herodotus, acclaimed by some as the “Father of History,” was already in antiquity denounced by others as the “Father of Lies.” Ancient religion as well as ancient morality show awareness of the danger. — Bernard Lewis, From Babel to Dragomans, 489
