"Baw is a pure Magian name and is a transcription of the Avesta _Bangha_
(Yesht 13,124). Another transliteration of the same word is Bohak, a
name borne by a hero of Ispahan who with his six sons and an army joined
Ardeshir (_Karnamak_ 4, 3, p. 22-19; Neoleke 46). It was also the name
of a son of Hobakht, the chief _Mobed_ under Shapur II. Bahak, son of
Fredon, was the ancestor of Aturpat Mahraspand (Bundahesh 33; West
Pahlavi Texts 1, 145). Another form of the same name is B[=a]we, who was
the _Astabed_ or _magister officiorum_ of the Persians (Josua Stylite
ed. Wright 59). The first ruler of the Bawend dynasty who enters history
is Sharwin ibn Surkhab (Tabari 3, 519). By the Arabs he was at first
made a vassal controlling the slopes of the Alburz (Ibn al Faqih 304;
Yakut 3, 283), and probably assumed the title _Padashkhwargar-shah_
which his descendants continued to hold in the time of al Beruni
(_Chronology,_ p. XL, No. 7). In Yakubi (vol. 2, 479) he even bears the
title of King of Tokharistaxi. After him is named Mount Sherwin on the
boundary of Komish (Tabari 3, 1275; Ibn al Fakih 305; Belazuri 339, 7).
In the year 201, that is, A.D. 816-17, however, the governor of
Tabaristan, Abdallah Ibn Khurdadbeh, the father of the historian and
geographer, invaded Larijan and Sarijan and annexed them to the empire
of Islam. He likewise conquered the mountain land of Tabaristan and
compelled Shahryar, the son of Sherwin, to surrender (Tabari 3, 1014).

"But after the death of Shahryar, in 825-26, Maziyar Ibn Qaren contested
the kingdom with his son Shapur and in alliance with the Moslems invaded
Mount Sherwin, captured the sons of Shahryar and put them to death.
(Tabari 3, 1093, Belazuri 339 and Ibn al Fakih 309.) However, a son of
Shahryar named Qaren who had been detained at the court of Maziyar later
