Hermetica in the context of "Macrocosm and microcosm"

The Nag Hammadi library (also known as the Chenoboskion Manuscripts and the Gnostic Gospels) is a collection of early Christian and Gnostic texts discovered near the Upper Egyptian town of Nag Hammadi in 1945.

Twelve leather-bound papyrus codices (and a tractate from a thirteenth) buried in a sealed jar were found by an Egyptian farmer named Muhammed al-Samman and others in late 1945. The writings in these codices comprise 52 mostly Gnostic treatises, but also three works belonging to the Corpus Hermeticum, and a partial translation/alteration of Plato's Republic. In his introduction to The Nag Hammadi Library in English, James Robinson suggests that these codices may have belonged to a nearby Pachomian monastery and were buried after Saint Athanasius condemned the use of non-canonical books in his Festal Letter of 367 A.D. The Pachomian hypothesis has been further expanded by Lundhaug & Jenott (2015, 2018) and further strengthened by Linjamaa (2024). In his 2024 book, Linjamaa argues that the Nag Hammadi library was used by a small intellectual monastic elite at a Pachomian monastery, and that they were used as a smaller part of a much wider Christian library.

Hermeticism, or Hermetism, is a philosophical and religious tradition rooted in the teachings attributed to Hermes Trismegistus, a syncretic figure combining elements of the Greek god Hermes and the Egyptian god Thoth. This system encompasses a wide range of esoteric knowledge, including aspects of alchemy, astrology, and theurgy, and has significantly influenced various mystical and occult traditions throughout history. The writings attributed to Hermes Trismegistus, often referred to as the Hermetica, were produced over a period spanning many centuries (c. 300 BCE – 1200 CE) and may be very different in content and scope.

One particular form of Hermetic teaching is the religio-philosophical system found in a specific subgroup of Hermetic writings known as the 'religio-philosophical' Hermetica. The most famous of these are the Corpus Hermeticum, a collection of seventeen Greek treatises written between approximately 100 and 300 CE, and the Asclepius, a treatise from the same period, mainly surviving in a Latin translation. This specific historical form of Hermetic philosophy is sometimes more narrowly referred to as Hermetism, to distinguish it from other philosophies inspired by Hermetic writings of different periods and natures.

The Corpus Hermeticum is a collection of 17 Greek writings whose authorship is traditionally attributed to the legendary Hellenistic figure Hermes Trismegistus, a syncretic combination of the Greek god Hermes and the Egyptian god Thoth. The treatises were originally written between c. 100 and c. 300 CE, but the collection as known today was first compiled by medieval Byzantine editors. It was translated into Latin in the 15th century by the Italian humanist scholars Marsilio Ficino (1433–1499) and Lodovico Lazzarelli (1447–1500).

Although the Latin word corpus is usually reserved for the entire body of extant writings related to some author or subject, the Corpus Hermeticum contains only a very small selection of extant Hermetic texts (texts attributed to Hermes Trismegistus, commonly known as Hermetica). Its individual treatises were quoted by many authors from the second and third centuries on, but the compilation as such is first attested only in the writings of the Byzantine philosopher Michael Psellus (c. 1017–1078).

Hermes Trismegistus (from Ancient Greek: Ἑρμῆς ὁ Τρισμέγιστος, "Hermes the Thrice-Greatest") is a legendary Hellenistic period figure that originated as a syncretic combination of the Greek god Hermes and the Egyptian god Thoth. He is the purported author of the Hermetica, a widely diverse series of ancient and medieval pseudepigraphica that laid the basis of various philosophical systems known as Hermeticism.

The wisdom attributed to this figure in antiquity combined a knowledge of both the material and the spiritual world, which rendered the writings attributed to him of great relevance to those who were interested in the interrelationship between the material and the divine.

The Asclepius, also known as the Perfect Discourse (from the Greek Logos teleios), is a religio-philosophical Hermetic treatise. The original Greek text, which was likely written in Alexandria between 100 CE and 300 CE, is largely lost and only a few fragments remain. However, the full text is extant in an early Latin translation, and fragments from a Coptic translation have also been found among the documents discovered in Nag Hammadi.
