In the present organization of the Writings in the Archives, their listing in catalogs {INVENTORY}, {LEGOMENA}, and {SCHOLIA} are subdivided into four eras that articulate their relation to each other in time, as deduced from their contents. Since the time of the Scholar who first presented the Archives to the world, these eras have been called 'timeBands', apparently analogizing this relation to the appearance of different layers of the earth laid down over eons. Applying this analogy, previous Curators have listed the Authors in descending order — that is, the more recent Authors are placed closer the top, the older ones nearer the bottom.
