House of Viseh (Persian: خاندان ویسه) is the most important Turanian clan in Shahnameh and Persian mythology. They are descendants of Tur. Tur is father of Zadashm and grandfather of Viseh. Viseh is the leading member of this clan. Viseh first war with Qaren is in the Iran-Turan war, both of which are not alive in Shahnameh afterwards.
The Viseh family is different from the Afrasiab family in the Shahnameh. Viseh is a great clan of the Visehgan dynasty and the Minister of the Pashang. But in the Iran-Turan war Viseh and Afrasiab, attack together. The Vishu and Afrasiab tribes appear to be of one race and two separate tribes
All of the members of this clan were killed in the battle of Davazdah Rokh. This incident was the beginning of Turan's decline and fall.[1][2]
