I have a beautiful horologe or hourglass filled with black sand. I imagine that the sand comes from Kaimu Beach. Hourglasses were used both to keep track of time and for navigation. Although assumed to have been used in the 3rd century and carried around as timepieces the first evidence of the existence of the hourglasse was in 1338, depicted in a fresco by Ambrogio Lorenzetti. Ferdinand Magellan kept 18 hourglasses per ship as he navigated the globe. How did I learn this? Lost in Wikipedia of course! Fascinating!! My hourglass does not help me with navigation unfortunately but it is a constant reminder for me to slow down. When it was new to me I used it daily to block an hour of uninterrupted writing time. Over the years that ritual has slowly unraveled as have many resolutions made at the end of years past. I do love this time of year because, at least for me, it is a time for renewal and new goals, some which will be met and some not. Gradually over the years it seems that I slowly meet a few more. Time to turn the hour glass over again.
