Hermetic

As above, so below — the line comes from the Emerald Tablet, attributed to Hermes Trismegistus, a figure who fused the Greek messenger god with the Egyptian Thoth. The real texts, the Corpus Hermeticum, are Greco-Egyptian, written centuries after either tradition alone, and vanished from the West until a 15th-century Florentine scholar translated them and reshaped the Renaissance.

The language beneath language.
