atomic model had baroque combination of components

An example of metaphor used in scholarship about science:

"Bohr's first model of the atom includes a nonconventional compromise between classical mechanics and electrodynamics on the one hand, and Planck's 'quantum rules' on the other hand. It has often been regarded as 'incoherent' due to its baroque combination of electronic stationary orbits ruled by classical mechanics, quantised transitions from one orbit to another, and overt violation of certain theorems of classical electrodynamics (since electrons on stationary orbits were supposed to emit no radiation despite their angular acceleration)."
