Athena (also: Athene) is a goddess of the organization of the city-state. This manifests in two parts. On one level, Athena commands the refined peace of the city-state. She presides over the organization of craftsmen (carpenters, weavers, potters, etc) whose skills are necessary for industrial life. She is, in a broader sense, the goddess of technology and the cultivation of practical arts and sciences. Finally she guides the citizenry when they assemble in their social clubs or as the body politic. On the other side of the coin, Athena is the fierce warrior goddess. She is the mistress of heavily armored hoplites who fight shoulder to shoulder with spear and sword. She is the goddess of strategy, hoping to discover and exploit the weak point of an enemy's advance. What brings this all together - productive peace and defensive war - is the intellect, valor and prudence needed to organize city-dwelling men for the survival and prosperity of their community.
Athena is usually portrayed as goddess of 'wisdom,' but she is more a goddess of counsel and strategy. She guides the various heroes of Greek mythology - Hercules, Theseus, Odysseus - in their journeys and their struggles against their adversaries. There is also a sort of strategic planning that is involved in any craft; the craftsman must have a clear idea of what is to be constructed, and then find the best way to assemble the available materials to achieve that end. The more abstract type of wisdom we associate with philosophy and moral advice, or even poetic truth, is instead under Apollo's protection in the Greek world.
Minerva was equated with Athena early on by the Romans, Indeed, an Etruscan version of Athena, Menrva, is probably the basis for the Roman cult of Minerva. But there are appreciable differences between Minerva and Athena. Minerva is much more the arch-intellect than Athena, and much less the warrior goddess.
Minerva is, like Athene, a goddess of crafts; but she is much more. As the goddess of handicrafts, she is also the goddess of organized trade guilds in the Roman state, and thus has a small hand in commerce. Going beyond this, she is the goddess of all intellectual endeavors. She is the goddess of teachers as well as students. She is also, in early Rome, the goddess of arts. Her shrine on the Aventine was home to a guild of poets and actors; in the Greek world, these people would have instead paid homage to Apollo and Dionysus, respectively. It was only later in Roman history that Apollo and Bacchus (Dionysus) made inroads as patrons of poets and literati. For early Roman history, Minerva's divine provinces were vast and she was, as Ovid phrased it, "the goddess of a thousand works."
Minerva was identified with Athena in Roman literature, and thus embodied the martial ethic in strategic terms. However, in practice the Romans already had two very powerful war gods with large cults: Mars and Bellona. Meanwhile, Jupiter was the god of victorious Roman generals and of the quintessential Roman military triumph. Minerva's association with war was secondary and eclipsed by these other deities. Italians outside of Rome may not have even invested Minerva with warlike attributes.
Minerva and Athene are probably the same deities; but they emphasize different aspects within their respective cultural and religious systems. Athene is a much more focused and practical goddess, while Minerva is much broader. In the Greek city-states, Athene was the patron of the craftsman and the citizen-soldier, a goddess of intelligent organization and prudent counsel, but one who yielded more abstract intellectualization and poetic arts to other deities. In Rome, Minerva presided over artists, artisans and intellectual life in general. As the cults of other Greek deities, such as Apollo and Dionysus, did not make appreciable inroads into Rome until later in its history, the arts and intellectual life as they existed in early Rome fell to Minerva.
The Greek Athena can leave me feeling cold. I understand her importance to the ancient Greek city-state, but as I am neither a craftsman nor a soldier her modern relevance is not always obvious. However, as someone interested in all forms of art and writing, as well as having general intellectual interests, I find the Roman Minerva more appealing to someone of modern tastes. She certainly deserved her place as a member of the Capitoline Triad, the official patrons of the Republic, as well as generally having been one of the most widely venerated deities in Rome. More to the point, she deserves to have a large cult following in the modern world.
