* Squealer: He is the main propagandist on the farm, skilled at twisting the truth and manipulating the animals' understanding of events. He is also a good writer, authoring the Seven Commandments and various revisions of the farm's history.
* Snowball: He is more of a revolutionary and intellectual figure who promotes literacy and education on the farm. He also designs the windmill plans. However, he is eventually driven out by Napoleon and his supporters.
Therefore, while neither is a dedicated poet, Squealer and Snowball both play important roles in shaping the farm's narrative and controlling information through writing.
