Marriages
Parandzem was married to the Arsacid prince Gnel, a nephew of King Arshak II of Armenia. Most likely in 358, Gnel returned from being held as a hostage in the Eastern Roman court, along with another Arsacid price, Tirit. According to the story given in the 5th-century Epic Histories (Buzandaran Patmutʻiwnkʻ), which drew from epic sources and whose account was influenced by romantic oral traditions, Tirit fell in love with Parandzem, who was "greatly renowned for her beauty and her modesty". Tirit slandered Gnel to Arshak, telling the king that Gnel desired the throne and had the support of the nobility. As a result, Arshak ordered Gnel's murder. Then, discovering Tirit's actions, Arshak had him put to death as well and took Parandzem as his own wife. According to Nina Garsoïan, "The romantic tale of love and jealousy related by the Armenian sources […] has obscured the implication, found in Movsēs Xorenacʻi, that, as Aršakuni sepuhs [junior princes] entitled to wear the crown, both Gnel and Tiritʻ were possible foci of rebellion against the king." The killing of Gnel and Tirit occurred in 359. The Armenian sources also report that Parandzem murdered Arshak's other wife, the Roman noblewoman Olympias, out of jealousy. Parandzem is said to have poisoned Olympias by mixing poison into the bread of the Eucharist, which was served to Olympias by a complicit priest. However, some scholars doubt the story about Parandzem's murder of Olympias.
There is disagreement between the two main Armenian sources, the Epic Histories and the history of Movses Khorenatsi, on the order of Parandzem's marriages. Both state that Parandzem married Arshak II after Gnel's murder, but they disagree on whether she was Arshak's first or second wife. Arshak had more than one wife simultaneously despite his Christian faith and in accordance with Iranian tradition. Chronological problems are created by the fact that Parandzem's son by Arshak, Pap, is said to have been born after the murder of Gnel and the marriage of Arshak and Parandzem in 359, but other biographical details about Pap indicate that he was born much earlier than 360. According to Garsoïan, a possible explanation is that Arshak married Parandzem earlier and had Pap with her around 350, then passed her to Gnel in an Iranian-style temporary marriage and later took her back after Gnel's death. While Arshak was also married to Olympias, Parandzem may have occupied an inferior place among Arshak's wives, and then taken the full rank of queen of queens (tikin tiknantsʻ) after Olympias's murder, which Garsoïan places after the death of Constantius II in 361. Albert Stepanyan (who does not address the issue of Pap's date of birth) instead proposes that Parandzem passed to Arshak after Gnel's death since "as the head of the Arsacid clan, [Arshak] was obliged to marry the widow of his nephew, to protect his property and pass it on to a legal son." Under this type of marriage, which is called stūr ī būtak in Sasanian sources, Pap would be considered Arshak's natural son but Gnel's legal son.
