ORIGINS AND ETYMOLOGY
Astro-English: from Astronese, the word Sideria is based on the adjective sidereal which denotes “the distant stars” but is used here in a more general sense “to denote the astronomical world”; in the context of the Astroeschatology and with the addition of the suffix -ia denoting a condition, the word Sideria comes to mean “the instance of the closure of the scope window.”
