"Cathy Haynes observed the eyes of several sheep, noting that 'it was late in the day, it still felt fairly bright outside. At this stage the ewes' pupils were a narrow pill shape.' After 45 minutes, she found that 'the ewes' pupils had morphed into rounds.'"
"Haynes cites an essay by Nina Gockerell, titled 'Telling Time Without a Clock,' which sparked her interest in how animals can help humans gauge time without traditional timepieces."
Sheep serve a dual purpose by keeping lawns mowed and offering a unique method of timekeeping. Cathy Haynes discusses this in her book, highlighting how sheep's pupils change shape throughout the day. Observations reveal that as daylight wanes, the pupils transition from narrow to round. Haynes's research extends beyond sheep, exploring various natural methods of timekeeping, including art installations. While sheep cannot replace a watch, they provide an interesting perspective on understanding the passage of time.
