Around 307/306 BCE, Epicurus bought a house and garden outside Athens and began teaching there. The Garden became the main center for Epicurean materialism: the view that everything is made of matter (atoms and void) and that natural explanations are enough. Its private setting also helped create a stable community that could preserve the school’s doctrines over time.
Epicurus wrote short letters and summaries that set out Epicurean physics (nature) and ethics (how to live well). Later authors report that Diogenes Laertius preserved three letters and the “Principal Doctrines,” a set of 40 maxims that helped standardize Epicurean teaching. These compact texts made Epicurean materialism easier to teach and transmit beyond Athens.
After Epicurus died in 270 BCE, his student Hermarchus became the next leader of the Garden. This leadership transition mattered because Epicureanism relied heavily on careful preservation of Epicurus’s core ideas rather than constant reinvention. Continuity under recognized successors helped keep Epicurean materialism coherent as it spread across the Hellenistic world.
By the mid-3rd century BCE, Polystratus became head of the Epicurean school at Athens and kept it institutionally stable. Fragments of his works survived among later finds at Herculaneum, showing that Epicurean arguments continued to be written, copied, and studied. This period reflects the school’s shift from founding insights to organized defense of a materialist worldview.
In the 2nd century BCE, some Epicurean philosophers were reportedly expelled from Rome, reflecting suspicion toward Greek philosophical teaching and its social effects. Even when details are disputed, these incidents show that Epicurean ethics—especially its focus on pleasure and its critique of superstition—could be politically controversial. The pushback also marked how Epicureanism was becoming visible beyond Greek cities.
By the late 2nd and early 1st century BCE, Zeno of Sidon was a prominent Epicurean teacher in Athens, known in part through Cicero’s reports. His career shows the Garden still functioning as a serious intellectual institution centuries after Epicurus. It also illustrates how Epicurean materialism and empiricism (knowledge based on sense experience) were refined during ongoing debates with rival schools.
In the 1st century BCE, the Roman poet Lucretius wrote De rerum natura (“On the Nature of Things”) to explain Epicurean philosophy in Latin. The poem presents a materialist universe of atoms and void and argues that understanding nature can reduce fear of gods and death. It became the most influential surviving ancient exposition of Epicurean materialism.
In the 1st century BCE, Philodemus (a student linked to the Athenian Epicurean scene) became active in Italy and wrote extensively on ethics, rhetoric, theology, and culture from an Epicurean perspective. His work helped adapt Epicurean materialism and ethics to Roman intellectual life. This made Epicureanism not just a Greek school but also a Roman cultural force.
In 79 CE, Mount Vesuvius erupted and buried Herculaneum, carbonizing but preserving a large library now called the Herculaneum papyri. Many of these rolls include works associated with Philodemus and other Epicurean writings. This accidental preservation became crucial for modern knowledge of Epicurean philosophy beyond a few famous summaries.
In the early Imperial era, Plutarch wrote several works attacking Epicurean ethics and theology, arguing that Epicurus’s approach could not support a truly happy or civic-minded life. These critiques show Epicureanism remained influential enough to be treated as a serious rival in moral philosophy. They also helped shape later perceptions of Epicurean materialism as socially and religiously suspect.
In the 2nd century CE, Diogenes of Oenoanda had a massive Epicurean inscription carved on a public structure in his city (in Lycia, modern Turkey). The inscription summarized Epicurean physics and ethics for residents and visitors, turning philosophy into a kind of public guide for living. Its scale shows that Epicurean materialism could still inspire organized community outreach in the High Roman Empire.
By the 3rd century CE, Epicurean communities and teaching appear less visible, while new religious and philosophical movements gained strength in the Roman world. Later Christian writers criticized Epicurus, often treating his materialism and non-providential gods (gods who do not govern the world) as a challenge to their theology. Even as an organized school declined, Epicurean materialist arguments continued to circulate as ideas to refute—or to reuse.
