Through Renaissance, Early modern period and Pythagoras

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, which were written in Egypt between approximately 100 and 300 CE. The most famous of these are the Corpus Hermeticum (a collection of seventeen Greek Hermetic treatises) and the Asclepius (a closely related treatise mainly surviving in a Latin translation). This specific, chronologically and geographically limited form of Hermetic philosophy is sometimes more narrowly referred to as Hermetism, to distinguish it from the philosophies inspired by the many Hermetic writings of a completely different period and nature.

A more open-ended term is Hermeticism, which may refer to a wide variety of philosophical systems drawing on writings attributed to Hermes, or even merely on subject matter generally associated with him. Most notably, alchemy often went by the name of "the Hermetic art" or "the Hermetic philosophy". A famous use of the term in this broader sense is in the concept of Renaissance Hermeticism, which refers to the wide array of early modern philosophies inspired by Marsilio Ficino's (1433–1499) and Lodovico Lazzarelli's (1447–1500) translation of the Corpus Hermeticum, as well as by Paracelsus' (1494–1541) introduction of a new medical philosophy drawing upon the 'technical' Hermetica (i.e., astrological, alchemical, and magical Hermetica, such as the Emerald Tablet). In 1964, Frances A. Yates advanced the thesis that Renaissance Hermeticism, or what she called "the Hermetic tradition", had been a crucial factor in the development of modern science. While Yates's thesis has since been largely rejected, the important role played by the 'Hermetic' science of alchemy in the thought of such figures as Jan Baptist van Helmont (1580–1644), Robert Boyle (1627–1691) or Isaac Newton (1642–1727) is now widely recognized.

Throughout its history, Hermeticism was closely associated with the idea of a primeval, divine wisdom, revealed only to the most ancient of sages, such as Hermes Trismegistus. During the Renaissance, this evolved into the concept of a prisca theologia or "ancient theology", which asserted that there is a single, true theology which was given by God to some of the earliest humans, traces of which may still be found in various ancient systems of thought. Thinkers like Giovanni Pico della Mirandola (1463–1494) supposed that this 'ancient theology' could be reconstructed by studying what were then considered to be the most ancient writings still in existence, such as those attributed to Hermes, but also those attributed to other ancient sages such as Zoroaster, Orpheus, Pythagoras, and Plato, as well as anonymous works such as the Chaldean Oracles and the Kabbalah. This soon evolved into the idea, first proposed by Agostino Steuco (1497–1548), that one and the same divine truth may be found in the religious and philosophical traditions of different periods and places, all considered to be different manifestations of the same universal perennial philosophy. In this perennialist context, the term 'Hermetic' tended to lose even more of its specificity, eventually becoming a mere byword for the purported divine knowledge of the ancient Egyptians, especially as related to alchemy and magic. This generic and pseudo-historical use of the term was greatly popularized by nineteenth- and twentieth-century occultists, despite their occasional use of authentic Hermetic texts and concepts.

Etymology

The term Hermetic is from the medieval Latin hermeticus, which is derived from the name of the Greek god Hermes. In English, it has been attested since the 17th century, as in "Hermetic writers" such as Robert Fludd.

The word Hermetic was used by John Everard in his English translation of The Pymander of Hermes, published in 1650.

Mary Anne Atwood mentioned the use of the word Hermetic by Dufresnoy in 1386.

The synonymous term Hermetical is also attested in the 17th century. Sir Thomas Browne in his Religio Medici of 1643 wrote: "Now besides these particular and divided Spirits, there may be (for ought I know) a universal and common Spirit to the whole world. It was the opinion of Plato, and is yet of the Hermeticall Philosophers." (R. M. Part 1:2)

Hermes Trismegistus supposedly invented the process of making a glass tube airtight (a process in alchemy) using a secret seal. Hence, the term "completely sealed" is implied in "hermetically sealed" and the term "hermetic" is also equivalent to "occult" or hidden.
