 His poems were published posthumously.

Transformations is a chamber opera in two acts by the American composer Conrad Susa with a libretto of ten poems by Anne Sexton from her 1971 book "Transformations", a collection of confessional poetry based on stories by the Brothers Grimm.
 Commissioned by Minnesota Opera, the work, which is described by its composer as "An Entertainment in 2 Acts", had its world premiere on 5 May 1973 at the Cedar Village Theater in Minneapolis, Minnesota.
 Anne Sexton, who had worked closely with Susa on the libretto, was in the audience.
 It went on to become one of the most frequently performed operas by an American composer with its chamber opera format of eight singers and an instrumental ensemble of eight musicians making it particularly popular with smaller opera companies and conservatories.
 The 2006 revival production of "Transformations" at the Wexford Opera Festival won the "Irish Times" Theatre Award for Best Opera Production.

al-Kumayt ibn Zayd al-Asadi (679/680-743 AD) was an Arabian poet from Kufa that used the language of the Bedouins to write poems in praise of the Umayyads, as well as 'Ali and his family.
 He was a schoolteacher at a local mosque until he was encouraged to write poetry instead.
 He wrote several series of poems including: his "Mudhahhaba", his "Malhama", and, arguably his most famous series, the "Hashimayyat" or "Hashirrnyyst".
 al-Kumayt was imprisoned by the caliph for his writings and escaped through the help of his wife.
 He later received a pardon from the caliph and was allowed to return to Kufa.
 While going to recite a poem, al-Kumayt was attacked by his Yemeni guards and killed.
 It is believed that the "Hashimayyat" and it’s supposedly pro-‘Alid poetry led to his assassination.
 While much of his poetry is controversial, it is generally not disputed that he wrote well of both the 'Alids and the Umayyads.
