Icône signification istya


Istya takes its name from the Greek goddess Hesita. In ancient times, the Greeks dedicated altars to Hestia in the center of towns and houses to remind them that she was always watching over them.

What’s more, to protect the future and avoid repeating the mistakes of the past, it’s essential to rely on knowledge. This is why Istya refers to the imperative of the verb oîda (“I know”) in Greek: isthe “know”, isthian “know”.
