“In our own world, filled with ubiquitous date marks, it is easy to underestimate the sheer novelty, and so historical significance, of this mass year-marking. But, in the ancient world, this was without precedent or parallel. In no other state in the ancient Mediterranean or west Asia did rulers and subjects inhabit spaces that were so comprehensively and consistently dated.” – Aeon
