It's a sundial - as the sun moves across the sky (or as the earth rotates on its axis around the stationary sun) the shadow of the gnomon moves across the dial and the markers indicate the time.
ReplyDeleteOh I see..what an invention!
ReplyDeleteAlso, I have learnt that, Ancient sundials first popped up in Egypt around some 1500 B.C
Thanks for sharing this antique!
