Did you know that #Roman road design included #safety features?
In the ruins of #Pompeii, you'll notice small white stones interspersed with the large paving ones along the extensive roads.
Those white #stones are 'cats eyes', i.e. gems that have a single line of inclusion of crystals of another mineral inside.
Upon light reflective on them (from the #moon), they enable the walker to see that they are still on the right path!

1. This is a photo of a road in the ruins in Pompeii. It shows a close-up of large dark grey paving stones, all of roughly the same size but without proper shaping. Between the large pavers are small, white stones, roughly the size of 2€ or 1 US$ coin. They are set inside the crevasses left between the large stones.
