The author Nashwan bin Sa'id al-Himyari was Qadi and scholar from Yemen, from a region north of San'a. He died in Yemen in 1178 AD (see Al-Zerekly, Al-A'lam, Biographical Dictionary, vol.8, p.20). Another copy of al-qasida al-himyariyya is in Prague at the National LIbrary (XVIII G 45). The qasida is listed there as the 'story of King Himyar and the building of the dam in Ma'rib, Yemen, written in verse and commented. The work also mentions about Alexander the Great and his rule'.
Tayma, where this manuscript was copied, is an oasis to the north-west of present-day Saudi Arabia.
