How did Horace use iambic verse in the Epodes?

In his collection titled the Epodes, Horace utilized iambic verse as a pioneer, adapting the style of the Greek poet Archilochus to suit his own literary objectives.1

Horace employed this meter for two primary purposes:
* Expression of Devotion: He used iambic verse to convey his dedication to his patron, Maecenas.1
* Brutal Invective: Following the tradition of Archilochus, he utilized the meter for harsh, aggressive criticism.1

Unlike his Greek models, who often used the form to vent raw personal feelings, Horace’s primary aim was the creation of deliberate, polished literature. His relationship with Archilochus was subtly allusive; this is evident in the aggressively iambic character found at the end of certain poems and his use of "Archilochean mottoes"—often placed at the beginning of an epode—to establish a thematic connection to his predecessor.12
