Blombos Time Ball is made with debris collected near Blombos cave in South Africa. It is inspired by time balls called Ititamat, or counting-the-days balls that the women of the Yakima and Klickitat people, Native American tribes based primarily in eastern Washington state, made to register essential events during their lives. The monthly menstrual cycle was indicated by singular straightforward knots, making it easy to count backward to find out when something happened precisely. In contrast, special events, like marriage, children, and moving house, were indicated by adding a unique pearl, a different rope, a stone, or a shell, depending on the symbolic meaning. Consequently, they could unwind their life story while recounting everything that happened from birth. The time balls were buried with the maker after death, symbolically and semantically linking to the human expression ‘being at the end of the rope.’ The label CIBh2 indicates the layer that was being excavated while I visited Blombos, reaching 100.000 BP.
