This chalcedony intaglio, dated to roughly AD 400 and attributed to the Sasanian Empire (AD 224–651), depicts a Zoroastrian fire altar rendered in three registers: a stepped pedestal, a central pillar, and an upper bowl presumably holding an eternal flame. A bird is positioned above the bowl, while two fish flank the pedestal base. The reverse bears an incised star motif. A drilled suspension hole indicates the stone functioned as a pendant, worn on a cord around the neck or wrist, making it simultaneously a devotional and personal ornament. Fire altars are among the most pervasive symbols in Sasanian glyptic art, appearing on coins, silver vessels, and seals to signal Zoroastrian religious identity and royal legitimacy; the Sasanian rulers styled themselves guardians of the sacred flame. The fish and bird elements introduce iconographic ambiguity. Both motifs appear in contemporaneous Christian art—fish as a well-documented early Christian symbol and birds (particularly doves) as emblems of the Holy Spirit—yet neither carries an exclusively Christian meaning in a Sasanian context. Scholars caution against reading the combination as evidence of religious syncretism without supporting textual evidence. Biblically, the Sasanian period overlaps with communities described in the Acts of the Apostles and the Pauline epistles as spreading through Mesopotamia and Persia, regions then under Parthian and later Sasanian rule; this artifact illuminates the broader religious environment those communities navigated. The stone is held at the Cleveland Museum of Art. Sources: Cleveland Museum of Art collection records; Rika Gyselen, Sasanian Seals and Sealings in the A.

This intaglio offers direct material evidence of Zoroastrian devotional practice at the personal level during the Sasanian period, the empire that governed the eastern diaspora regions touched by early Christian mission; its ambiguous bird-and-fish imagery also illustrates the interpretive challenges scholars face when distinguishing religious syncretism from shared decorative conventions in late-antique Iran.
