Tarikh-e Beyhaqi
Abul-Fazl Bayhaqi · 11th century CE
An 11th-century Persian court history by Abul-Fazl Bayhaqi that preserves rare surviving fragments of Biruni's lost history of Khwarazm.
This later court history is the only surviving source for excerpts of Biruni's own lost history of Khwarazm.

About this source
What it is
Tarikh-e Beyhaqi is a Persian history of the Ghaznavid Empire, written by Abul-Fazl Bayhaqi, a younger contemporary of Al-Biruni, in the 11th century. Only part of the original thirty books survives. The manuscript shown here is a later copy from the 17th-19th centuries, kept at the Library, Museum and Document Center of Iran's Parliament.
Why it matters
This book is one of the most important sources for Ghaznavid history and is admired as a masterpiece of Persian prose. For students of Al-Biruni, it matters because it preserves the only surviving excerpts of his own lost history of Khwarazm, the Musamara fi akhbar Khwarazm. Without Bayhaqi's work, that book by Biruni would be completely unknown to us.
