In his PhD thesis, Pouyan Rezvani presents a reconstructed, translated and annotated version of two medieval manuscripts about the astrolabe, an ancient astronomical instrument. Both works were authored by Al-Biruni (973-1048), one of the most prolific scientists of the Islamic Middle Ages. “Reconstructing the manuscripts was quite a puzzle, since the original copies were lost,” Rezvani explains. He will defend his PhD thesis, which he wrote under the supervision of Prof. Jan Hogendijk, on 25 September.
Of the 26 still existing works by Al-Biruni, 24 had previously been published. For his PhD research Rezvani reconstructed and translated the remaining two, and added context and explanation.
