DDLS speaker links artifacts to cosmos
In the southeastern portion of the rocks and wooden posts encircling Stonehenge
are the bones of animals and human cremations that were "placed carefully
in the post holes."
The placement of these objects correlates with the most southerly rising
of the moon.
"It mattered where they were putting them," said Clive Ruggles,
a professor of the School of Archaeology and Ancient History at the University
of Leicester in England and Tuesday’s featured speaker. "This
is evidence of what people were doing at the time."
Ruggles’ talk focused on archeological monuments and their relationship
with the cosmos.
His discussion titled "Archaeoastronomy — Stonehenge and Beyond"
enticed the audience Tuesday with examples of ancient monuments that have
some tie to the lunar or solar cycles. For example, the building of a
wooden trackway in England in 500 B.C. correlates with prominent lunar
eclipses at the time.
"If astrological events influenced people, then we have to ask ourselves
where and when," Ruggles said. In ancient monuments archaeologists
can begin to understand "how people conceived of space and time.
We can look at the diversity of how people observed the cosmos around
them."
Ruggles believes ancient perceptions of space, time and the cosmos provide
insight into life in prehistoric times. The sky was an integral part of
the environment by which time was measured and space organized. Figures
of cosmological importance often originated in the sky.
He pointed to ancient Mayan pyramids in Mexico as evidence of the link
between artifacts and the sky. The pyramids contain hieroglyphics that
indicate a Mayan astronomical almanac with an eclipse table.
"There is a whole list of artifacts that support archaeoastronomy,
the study of beliefs and practices about the history of the sky,"
Ruggles said.
Archaeologists are measuring monuments throughout southern Europe to gauge
whether the orientation or placement of the monuments has any significance
in relationship to the lunar or solar cycles. He said a colleague has
measured one of the Tomb of Giants: Li Lolghi is Sardinia’s largest
Giant’s Tomb (tomba di giganti). These monuments were constructed
all over the island from about 1900 B.C. to about 1000 B.C.
This collective burial chamber is very long, with a series of uprights,
and it was once covered with stones or earth. The tomb features a horned
semi-circular forecourt that was probably used as a meeting place for
rituals. Ruggles noted that the monuments all face the sunrise. He said
there is likely a connection between this burial site and the placement
of the sun.
The job of an archaeoastronomer, he said, is not to look for monuments
aligning with something in the cosmos because "you’ll always
find something that aligns." But rather a true archaeoastronomer
must look for trends and contextual information.
"We need to look at the diversity of how people observed the cosmos
around them," Ruggles said. "We have to look at it and understand
that there are different systems of thought."
Ruggles’ talk will be rebroadcast on Lab TV on Thursday at 10 a.m.,
noon, 2 p.m., 4 p.m. 8 p.m. and on April 5 at 4 a.m. For a tape of the
