Aratus’ didactic epos Phaenomena was very popular among Romans. Thus, it was translated into Latin by several Roman authors, among others by Marcus Tullius Cicero and Germanicus Iulius Caesar. Since the aim of a didactic poem is not only to delight the readers but also to teach them, the authors choose various structures while directing them. The paper focuses on instructive patterns used by Aratus and their implementation in Latin translations. Its aim is to find out whether Cicero and Germanicus used the same instructive patterns like Aratus when translating Phaenomena, or whether they changed the forms of instructions and perhaps adjusted them to the Roman audience.
