All in all, over 20,000 of Henrikson's daily poems were published in
Dagens Nyheter, some of which have subsequently been published in anthologies. Henrikson also wrote and published a number of other volumes of poetry, and a popular introduction to various metric forms and styles. His style was often humorous but could also be very serious; there were often several layers of meanings in Henrikson's texts. Henrikson's published production includes over 100 books including collections of poetry, history books retelling the history of, among others, Sweden, Denmark, China, Iceland and ancient Greece and Rome, and a general encyclopedia, which Henrikson started writing at the age of 80. He also translated poetry, opera librettos and other texts from languages including French, English, and Chinese. His translation of the libretto of
Mozart's
The Magic Flute from German into Swedish in 1968 became a classic, which was also used in
Ingmar Bergman's
movie version of the opera from 1975. ==Awards and prizes==
