Tertullian dismantles the Greco-Roman pantheon category by category -- physical, mythic, and national gods -- arguing that Rome's own scholars (Varro chief among them) already prove the gods are dead men, personified elements, or bureaucratic inventions.
Ad Nationes 2 is the second book of Tertullian's earliest surviving apologetic work, addressed "to the nations" of the Roman world rather than to any single magistrate. Where Book 1 answered the practical charges leveled at Christians (secrecy, cannibalism, disloyalty), Book 2 goes on the attack against the target of Christian refusal: the gods themselves. Tertullian adopts the Roman antiquarian Varro's own threefold division of theology -- physical (the gods of the philosophers), mythical (the gods of the poets), and civic or national (the gods each people adopts for itself) -- and works through each class in turn, then adds a fourth: the gods particular to Rome.
The argument unfolds as a sustained demolition using the enemy's own sources. Against the physical theologians, Tertullian shows that identifying gods with the elements (sun, moon, sea) makes them corporeal and therefore mortal, since eclipses and change prove decay. Against the poets' mythic gods, he catalogues the incest, adultery, and violence of Jupiter's family and asks why such conduct is shrugged off as "poetic license" for gods but never forgiven in men. Against the national and Roman gods, he runs through deified Caesars, obscure functional deities (a god for the threshold, a goddess for weaning infants), and grubby founding legends -- Romulus's fratricide, Hercules's mistress the harlot Larentina, the manufactured cult of Serapis -- arguing that if divinity can be voted in by a senate of the dead, someone even higher must be doing the admitting. The closing chapters turn to Rome's imperial success itself, refuting the claim that Roman piety earned Roman empire by pointing out that empires rise and fall by war, not by the favor of gods who could not even save their own native cities.
Historically, Ad Nationes matters as the rough draft of the more polished Apology that followed it: Tertullian reused much of this material after this pamphlet, tightening the rhetoric. It preserves, almost by accident, a wealth of otherwise-lost detail on Roman antiquarian religion -- Varro's classifications, obscure numina, the euhemerist reading of Saturn and Serapis -- making it a source document for Roman religious history even for readers with no stake in the theological argument. It also shows early Christian apologetic learning to fight on Roman turf, using Roman erudition (Varro, the Sibyl, historians like Cassius Severus) against Roman cult rather than simply asserting scripture against it.

“The Platonists make him one who cares for things, arbitrates, and judges; the Epicureans make him idle and unemployed, and, so to speak, nobody at all; the Stoics place him outside the world, the Platonists inside it.”

“It is not enough that they have even consecrated a man — I mean the one whom not Egypt or Greece alone, but the whole world now worships, and by whom the Africans swear”

“Indeed, Romulus both killed his own brother and stole other men's virgins by trickery.”

“Let those gods who lost their own cities go on protecting the city of Rome, if that is what Roman religion has earned!”

It is the second book of Tertullian's early two-book apologetic pamphlet Ad Nationes, and it takes on the Greco-Roman gods directly. Tertullian uses the Roman scholar Varro's own division of theology into physical, mythical, and civic (national) gods, then adds Rome's own peculiar pantheon as a fourth category, arguing that every class fails the test of true divinity.
Ad Nationes is the earlier and rougher work; the Apology reuses much of the same argument in more polished, better-organized form aimed at Roman magistrates specifically. Ad Nationes is addressed more broadly to the nations and spends far more space on detailed antiquarian refutation of individual gods, especially in Book 2.
Varro was Rome's leading antiquarian authority on religion, and his threefold theology (physical, mythical, civic) was the standard Roman framework. By adopting Varro's own categories and turning them against the gods, Tertullian argues from evidence Romans already accepted rather than importing an outside framework they could simply reject.
Euhemerism holds that gods began as real men later mythologized into deities. Tertullian applies this repeatedly -- to Saturn, to Serapis (traced to a historical Egyptian cult figure), to Hercules, to Romulus, and to the deified Roman emperors -- to argue that Roman religion is a record of flattery and political convenience, not genuine divinity.
No -- Tertullian argues the opposite. In the closing chapters he contends that empires rise and fall by war and circumstance regardless of a nation's piety, pointing out that many of Rome's own gods (Minerva at Athens, Apollo at Delphi) failed to protect their native cities from conquest, so Roman military success cannot be credited to divine favor.
He lists numerous minor functional gods invented to preside over single moments of life -- a god of conception (Conseuius), deities for weaning, for widowing, for stripping the eyes in death, and gods tied to specific city locations -- using their narrow, almost administrative scope as evidence that they were invented to fill gaps rather than discovered as real powers.
Despite its polemical purpose, yes, in part: it preserves quotations and classifications from Varro, Dionysius the Stoic, Arcesilaus, and other sources that survive today largely or only through Tertullian's citation, making Ad Nationes 2 valuable evidence for Roman antiquarian theology even independent of its Christian argument.
The title itself signals it: "to the nations," meaning the broader Greco-Roman public rather than a single official, unlike works addressed to a named governor. Tertullian writes as if debating any educated pagan reader familiar with standard Roman religious and literary authorities.
