Keraunography is not a widely recognized term in established academic, scientific, or artistic literature. No reliable encyclopedic sources provide a definition, historical usage, or detailed discussion of the concept.
Possible etymology
The word appears to be a compound of the Greek roots kéraunos (κέραυνος), meaning “thunderbolt” or “lightning,” and ‑graphy (‑γραφία), a suffix denoting “writing,” “recording,” or “representation.” By this construction, the term could plausibly refer to the depiction, study, or recording of lightning phenomena.
Potential contextual usage
While the term does not appear in standard dictionaries or scholarly databases, it might be employed informally in niche contexts—such as photography, meteorology, or artistic projects—to describe the practice of photographing, illustrating, or otherwise documenting lightning strikes. However, such usage is anecdotal and not documented in authoritative sources.
