• adj. 密封的；与外界隔绝的；不透气的；炼金术的
• n. 炼金术士

来自希腊语Hermes,古希腊神话中的智慧、艺术与技艺之神，与埃及神Thoth一起被古代的柏拉图主义者，神秘主义者和炼金术士奉为祖师爷，被称为Hermes Trismegistos,即Thrice-Great Hermes,因此，一种在炼金术中发明的密封玻璃管就此得名。

hermetic

hermetic: [17] Hermetic means literally ‘of Hermes’. Not Hermes the messenger of the Greek gods, though, but an Egyptian priest of the time of Moses, who in the Middle Ages was regarded as identical with the versatile Hermes in his capacity of patron of science and invention, and who was thus named Hermes Trismegistus ‘Hermes the thrice greatest’. This shadowy figure was the supposed author of various works on alchemy and magic, and so the term hermetic came to be roughly synonymous with alchemical.

One of the inventions credited to Hermes Trismegistus was a magic seal to make containers airtight, and by the 1660s we find hermetic being used for ‘airtight’.

hermetic (adj.)

c. 1600 (implied in hermetically), "completely sealed," also (1630s) "dealing with occult science or alchemy," from Latin hermeticus, from Greek Hermes, god of science and art, among other things, identified by Neoplatonists, mystics, and alchemists with the Egyptian god Thoth as Hermes Trismegistos "Thrice-Great Hermes," who supposedly invented the process of making a glass tube airtight (a process in alchemy) using a secret seal.
