The poem describes the night sky over Greece more than 2,500 years ago. “This is an example of where the scientific community can make a contribution to knowledge described in important ancient texts, ” said Manfred Cuntz, physics professor . “Estimations had been made for the timing of this poem in the past, but we were able to scientifically confirm the season that corresponds to her specific descriptions of the night sky in the year 570 B.C.” Sappho’s “Midnight Poem” describes a star cluster known as the Pleiades having set at around midnight, when supposedly observed by her from the Greek island of Lesbos.
…The moon has set
And the Pleiades;
It is midnight,
The time is going by,
And I sleep alone.
(Henry Thornton Wharton, 1887:68)
Cuntz and Levent Gurdemir, director of the Planetarium at UTA, used advanced software called Starry Night v7.3, to identify the earliest date that the Pleiades would have set at midnight or earlier in local time in 570 B.C. The Planetarium system Digistar5 also allows creating the night sky of ancient Greece for Sappho’s place and time.”Levent Gurdemir said “This is an example of how we are opening up the Planetarium to research into disciplines beyond astronomy, including geosciences, biology, chemistry, art, literature, architecture, history and even medicine.”
The Starry Night software demonstrated that in 570 B.C., the Pleiades set at midnight on Jan25, which would be the earliest date that the poem could relate to. As the year progressed, the Pleiades set progressively earlier. “The timing question is complex as at that time they did not have accurate mechanical clocks as we do, only perhaps water clocks” said Cuntz. “For that reason, we also identified the latest date on which the Pleiades would have been visible to Sappho from that location on different dates some time during the evening.”
The researchers also determined that the last date that the Pleiades would have been seen at the end of astronomical twilight – the moment when the Sun’s altitude is -18 degrees and the sky is regarded as perfectly dark – was March31. “From there, we were able to accurately seasonally date this poem to mid-winter and early spring, scientifically confirming earlier estimations by other scholars,” Cuntz said.
Sappho was the leading female poet of her time and closely rivaled Homer. Her interest in astronomy was not restricted to the “Midnight Poem.” Other examples of her work make references to the Sun, the Moon, and planet Venus. “Sappho should be considered an informal contributor to early Greek astronomy as well as to Greek society at large,” Cuntz added. “Not many ancient poets comment on astronomical observations as clearly as she does.” http://www.uta.edu/news/releases/2016/05/Cuntz-dating-poem.php
