the open sky, ascending mounds to light their fires (The Histories, i.131). Strabo confirms this, noting that in the 6th century, the sanctuary at Zela in Cappadocia was an artificial mound, walled in, but open to the sky (Geographica XI.8.4.512). By the Parthian era (250 BCE–226 CE), Zoroastrianism had in fact two kinds of places of worship: One, apparently called bagin or ayazan, sanctuaries dedicated to a specific divinity, constructed in honor of the patron Yazata of an individual or family and included an icon or effigy of the honored. The second were the atroshan, the "places of burning fire", which as Boyce (1997:ch. 3) notes, became more and more prevalent as the iconoclastic movement gained support. Following the rise of the Sassanid dynasty, the shrines to the Yazatas continued to exist, with the statues—by law—either being abandoned as empty sanctuaries, or being replaced by fire altars (so also the popular shrines to Meher/Mithra which retained the name Darb-e Mehr—Mithra's Gate—that is today one of the Zoroastrian technical terms for a fire temple). Also, as Schippman observed (loc. Cit. Boyce, 1975:462), even during the Sassanid era (226–650 CE) there is no evidence that the fires were categorized according to their sanctity. "It seems probable that there were virtually only two, namely the Atash-i Vahram [literally: "victorious fire", later misunderstood to be the Fire of Bahram, see Gnoli, 2002:512] and the lesser Atash-i Adaran, or 'Fire of Fires', a parish fire, as it were, serving a village or town quarter" (Boyce, 1975:462; Boyce 1966:63). Apparently, it was only in the Atash-i Vahram that fire was kept continuously burning, with the Adaran fires being annually relit. While the fires themselves had special names, the structures did not, and it has been suggested that "the prosaic nature of the middle Persian names (kadag, man, and xanag are all words for an ordinary house) perhaps reflect a desire on the part of those who fostered the temple-cult [...] to keep it as close as possible in character to the age-old cult of the hearth-fire, and to discourage elaboration" (Boyce, 2002:9). The Indian Parsi-Zoroastrian practice of rendering the term athornan (derived from the Avestan language "athravan") as "fire-priest" in the English language is based on the mistaken assumption that the athra* prefix derives from atar (Boyce, 2002:16–17). The term athravan does not appear in the Gathas, where a priest is a zaotar, and in its
