This is not a direct answer to what you asked, but there is very good reason for the lack of mention of Roman or other foreign gods in the Talmud. As Maimonides wrote:
The idolaters compiled many books of worship, defining its principle manner of service, its works and its laws; but the Holy One, blessed be He! charged us not to read those books at all, not to think of idolatry generally nor of aught of its details. Moreover, to look at it is forbidden, as it is said: "Turn ye not unto idols" (Lev. 19.4.); and of thinking on this subject it is said: "And that thou inquire not after their gods, saying, How did these nations serve their god"? (Ibid.), which is a warning that thou shalt not inquire concerning its manner of practice, though thou art not worshiping it, for this very inquiry causes a turning after it and to imitate their practice, as it is further said: "Even so will I do likewise" (Ibid.).
In a comment you said that you were not given a choice of topic, but it might be worth explaining to whoever assigned the essay that their assignment is not realistic, as the Talmud is completely uninterested in the falsehoods of the Romans, and considered their study a complete waste of time.
The Sages taught in a baraita: With regard to writing that is under a picture or under graven images [deyokenaot], it is prohibited to read it on Shabbat lest one end up reading business documents. And with regard to an idolatrous image itself, even on a weekday it is prohibited to look at it, because it says: “Do not turn toward idols [al tifnu el ha’elilim] or make yourselves molten gods, I am the Lord your God” (Leviticus 19:4). The Gemara asks for clarification: What is the biblical derivation? How does this verse indicate that one may not look at an idolatrous image? Rabbi Ḥanin said: Do not push God [al tefannu El] out of your mind by looking at these images.
