Hermetic seal - Wikipedia, the free encyclopedia
.
The word hermetic comes from the syncretism of the Greek god Hermes and the Egyptian Thoth; this figure was also a mythological alchemist known as Hermes Trismegistus. The latter has two books attributed to him, the Emerald Tablet and the Corpus Hermeticum. He was believed to possess a magic ability to seal treasure chests so that nothing could access their contents.
