Antiomno was the king of the land of Middoni, where Ammon’s brother Aaron and companions were imprisoned (Alma 20:2-4). When Ammon and King Lamoni traveled to the land of Middoni, Lamoni said that Antiomno was a friend to him, and that he would “flatter the king of the land, and he will cast thy brethren out of prison” (Alma 20:4).
This suggests that Antiomno was on good terms with King Lamoni and was willing to release Ammon’s brethren from prison at Lamoni’s request. The text does not provide any further details about Antiomno’s character or background, but it is clear that he held political power as the king of the land of Middoni and had a friendly relationship with King Lamoni (Alma 20:4).
