    Some people consider this to be the oldest surviving photograph. There was a fashion in Italy where artists used a 'camera obscura' to help them draw accurately.

    Photoreactive chemicals were known (could be derived from seaweed and silver). It would be a simple step to think of putting this chemical on canvas and "photographing" a statue or something immobile.
