Within the Analyst school were two camps: proponents of the "lay theory", which held that the "Iliad" and the "Odyssey" were put together from a large number of short, independent songs, and proponents of the "nucleus theory", which held that Homer had originally composed shorter versions of the "Iliad" and the "Odyssey", which later poets expanded and revised. A small group of scholars opposed to the Analysts, dubbed "Unitarians", saw the later additions as superior, the work of a single inspired poet. By around 1830, the central preoccupations of Homeric scholars, dealing with whether or not "Homer" actually existed, when and how the Homeric poems originated, how they were transmitted, when and how they were finally written down, and their overall unity, had been dubbed "the Homeric Question".
