Ahasuerus

Ahasuerus (/əˌhæzjuˈɪərəs/ ə-HAZ-ew-EER-əs; Hebrew: אֲחַשְׁוֵרוֹשׁ, Modern: ʾĂḥašverōš, Tiberian: ʾĂḥašwērōš, commonly Achashverosh; Koine Greek: Ἀσουήρος, romanized: Asouḗros, in the Septuagint; Latin: Assuerus in the Vulgate) is a name applied in the Hebrew Bible to three rulers of Ancient Persia and to a Babylonian official (or Median king) first appearing in the Tanakh in the Book of Esther and later in the Book of Tobit. It is a transliteration of either Xerxes I or Artaxerxes I; both are names of multiple Achaemenid dynasty Persian kings.
The Hebrew form is believed to have derived from the Old Persian name of Xerxes I, Xšayāršā (< xšaya 'king' + aršan 'male' > 'king of all male; Hero among Kings'). That became Babylonian Aḫšiyâršu (𒄴𒅆𒐊𒅈𒋗, aḫ-ši-ia-ar-šu) and then Akšîwâršu (𒀝𒅆𒄿𒈠𒅈𒍪, ak-ši-i-wa6-ar-šu) and was borrowed as Hebrew: אֲחַשְׁוֵרוֹשׁ, romanized: Ăḥašwēroš and thence into Latin as Ahasuerus, the form traditionally used in English Bibles. The Persian name was independently rendered in Ancient Greek as Ξέρξης Xérxēs. Many newer English translations and paraphrases of the Bible have used the name Xerxes.
"Ahasuerus" is given as the name of a king, the husband of Esther, in the Book of Esther. He is said to have "ruled over a hundred and twenty-seven provinces from India to Nubia" – that is, over the Achaemenid Empire. Some consider the narrative of Esther was to provide an aetiology for Purim, and that the name Ahasuerus is usually understood to refer to Xerxes I, who ruled the Achaemenid Empire between 486 and 465 BC. Outside of the book of Esther, history records that Xerxes was married to Amestris, not Vashti or Esther. Moreover, it is understood that Persian kings did not marry outside a restricted number of Persian noble families. In the Septuagint, the Book of Esther refers to the king as 'Artaxerxes', who was the younger son of Xerxes (Ancient Greek: Ἀρταξέρξης).
Numerous scholars have proposed theories as to who Ahasuerus represents. Most scholars today identify him with Xerxes I, as did 19th-century Bible commentaries. Three factors, among others, contribute to this identification:
While today the king of Esther is usually identified as Xerxes I, the ancient traditions identify him with his son, Artaxerxes I. The Septuagint, the Vulgate, the Midrash of Esther Rabbah, I, 3, and the Josippon identify him as Artaxerxes. Many historians and exegetes from ancient times and the Middle Ages also identified Ahasuerus with Artaxerxes I, including, most notably, Josephus, who relates that "Artaxerxes" was the name by which he was known to the Greeks. The Ethiopic text calls him Arťeksis, usually the Ethiopic equivalent of Artaxerxes.
Some have speculated that the king was Artaxerxes II. In his Chronography, the 13th century Syriac historian Bar Hebraeus also identifies Ahasuerus as Artaxerxes II citing the sixth century AD historian John of Ephesus. Plutarch in his Lives (AD 75) records alternative names Oarses and Arsicas for Artaxerxes II Mnemon given by Deinon (c. 360–340 BC) and Ctesias (Artexerxes II's physician) respectively. These derive from the Persian name Khshayarsha as do "Ahasuerus" ("(Arta)Xerxes") and the hypocorism "Arshu" for Artaxerxes II found on a contemporary inscription (LBAT 162). These sources thus arguably identify Ahasuerus as Artaxerxes II in light of the names used in the Hebrew and Greek sources and accords with the contextual information from Pseudo-Hecataeus and Berossus as well as agreeing with Al-Tabari and Masudi's placement of events.
Ahasuerus is also given as the name of a King of Persia in the Book of Ezra. Modern commentators associate him with Xerxes I who reigned from 486 to 465 BC. Other identifications have been made for Cambyses II or with Bardiya (Greek Smerdis) who reigned (perhaps as an imposter) for seven months between Cambyses II and Darius I.
Ahasuerus is given as the name of the father of Darius the Mede in the Book of Daniel. Josephus names Astyages as the father of Darius the Mede, and the description of the latter as uncle and father-in-law of Cyrus by mediaeval Jewish commentators matches that of Cyaxares II, who is said to be the son of Astyages by Xenophon. Thus this Ahasuerus is commonly identified with Astyages. He is alternatively identified, together with the Ahasuerus of the Book of Tobit, as Cyaxares I, said to be the father of Astyages. Views differ on how to reconcile the sources in this case. One view is that the description of Ahasuerus as the "father" of Darius the Mede should be understood in the broader sense of "forebear" or "ancestor". Another view notes that on the Behistun Inscription, "Cyaxares" is a family name, and thus considers the description as literal, viewing Astyages as an intermediate ruler wrongly placed in the family line in the Greek sources.
Most scholars view Darius the Mede as a literary fiction, or possibly a conflation of Darius the Great with prophecies about the Medes.
In some versions of the deuterocanonical Book of Tobit, Ahasuerus is given as the name of an associate of Nebuchadnezzar, who, together with him, destroyed Nineveh just before Tobit's death. A traditional Catholic view is that he is identical to the Ahasuerus of Daniel 9:1 In the Codex Sinaiticus Greek (LXX) edition, the two names in this verse appear instead as one name, Ahikar (also the name of another character in the story of Tobit). Other Septuagint texts have the name Achiachar. Western scholars have proposed that Achiachar is a variant form of the name "Cyaxares I of Media", who historically did destroy Nineveh, in 612 BC.
In some versions of the legend of the Wandering Jew, his true name is held to be Ahasuerus – even though the biblical king is not described as a Jew and nothing in the Biblical account of him is similar to that myth. This is the name by which Immanuel Kant refers to the Wandering Jew in The Only Possible Argument in Support of a Demonstration of the Existence of God.
