Hourglass is the fourteenth studio album of 2017.
 The first hourglasses were two separate bulbs with a cord wrapped at their union that was then coated in wax to hold the piece together and let sand flow in between
=== Early Middle Ages ===There are no records of the hourglass existing in Europe prior to the Early Middle Ages; the first documented example dates from the 8th century AD, crafted by a Frankish monk named Liutprand who served at the cathedral in Chartres, France
