theogony

This term describes a specialized academic or mythological framework focusing on the birth and lineage of divine beings. It carries a formal, scholarly tone and is primarily used in the context of classical studies, theology, or comparative mythology to categorize the structural history of a pantheon.

Because it refers to a specific type of narrative or a formal treatise, it is treated as a countable noun. When discussing multiple distinct mythological systems, one would refer to their respective theogonies.
