Zach's essay, “Thoughts on Alterman’s Poetry,” which was published in the magazine "Achshav" ("Now") in 1959 was an important manifesto for the rebellion of the "Likrat" ("towards") group against the lyrical pathos of the Zionist poets, as it included an unusual attack on Nathan Alterman, who was one of the most important and esteemed poets in the country. In the essay Zach decides upon new rules for poetry. The new rules that Zach presented were different from the rules of rhyme and meter which were customary in the nation’s poetry at the time.
