Descriptions of iron on turtle-ship roofs show why written testimony must be interpreted rather than treated as an engineering drawing. An author might mean plates, spikes, protected patches, or simply a surface that looked metallic, yet consider the distinction irrelevant to the battle story being recorded. Historians therefore compare perspectives, test claims against other evidence, and remain alert to what a writer chose not to explain. A surviving original hull would narrow the range of interpretation in a way that even numerous replicas and evocative accounts cannot.

Why written accounts cannot replace a surviving hull
The turtle-ship armour dispute becomes a lesson in source criticism: vivid historical language can preserve an impression while omitting the technical detail historians need.
