Origin
Mid 17th century; earliest use found in Charles Butler (1560–1647), philologist and apiarist. From ancient Greek παράθεσις juxtaposition, in Hellenistic Greek with reference to words in a sentence, also denoting comparison, mentioning of names, citation of instances, instance from παρα- + θέσις, after παρατιθέναι to place beside. In use as a rhetorical figure after post-classical Latin parathesis (636 in Isidore).
