Adonis joined ranks with Syro-Lebanese poet Yusuf al-Khal in editing "Majallat Shiʿr" (English: "Poetry Magazine"), a modernist Arabic poetry magazine, which Al-Khal established in 1957. His name appeared as editor from the magazine's fourth edition. By 1962 the magazine appeared with both Adonis and Al-Khal's names side by side as "Owners and Editors in Chief". While at "Shiʿr", Adonis played an important role in the evolution of free verse in Arabic. Adonis and al-Khal asserted that modern verse needed to go beyond the experimentation of "al-shiʿr al-hadith" (modern, or free, verse), which had appeared nearly two decades earlier.
