Ancient Greece - Astronomical Knowledge

Did Ancient Greeks use Venus Calendar to Track Pregnancy?

Research has suggested that a calendar based on the movement of planet Venus was used in the daily lives of people in ancient Aegean civilizations about 4,000 BC, and may have even been used to track milestones during pregnancy.  

Neolithic objects in the shape of ‘frying pans’ that were found in Greece, were decorated with concentric circles, spirals, radial patterns and sometimes rowing vessels. Professor of space physics, Minas Tsikritsis, suggested at the 21 st International Conference of SEAC (Societe Europeenne pour l’Astronomie dans la Culture) that the objects were used as calendars to perform astronomical calculations of the orbits of Venus, Jupiter, Mars and the Sun.

The use of the frying-pan object, whose shape is believed to be symbolic, was used to associate activities and events in life with the environment and astronomical events.

Furthermore, according to Professor Tsikritsis, it appears that during the Neolithic era the ancient Greeks not only knew that Earth requires 365 days to make a complete circuit around the Sun, but also that Venus needs 584 and Jupiter 399.

The interesting thing is that it looks that the movement of the planet Venus was correlated to the biological cycle of pregnancy. Planet Venus (related to Goddess Aphrodite) appears before the sunrise for 263 days (approximately 9 moon months) and another 265 days after the sunset. So half of Venus cycle is approximately 9 months which coincides with the biological cycle of human pregnancy. Adding to that, it can be seen that on some of the objects triangles and other symbols were engraved next to specific days of the calendar, and some even had engravings in the shape of the female uterus. This suggests that such a calendar was used by women to determine if they were pregnant or not, as well as tracking the milestones of their pregnancy.

It seems that people of this era in Greece had advanced astronomical knowledge and used multiple complex calendars for many different reasons, including the famous Antikythera Mechanism .

In a recent article on Ancient Origins, Jason Jarrell and Sarah Farmer discussed the possibility that Zecharia Sitchin mistranslated several Sumerian Texts. According to Sitchin, there were a number of Sumerian seals that relate to the Anunnaki, whom he said came from the heavens to create man and enslave mankind to work in the mines.

Our Mission

At Ancient Origins, we believe that one of the most important fields of knowledge we can pursue as human beings is our beginnings. And while some people may seem content with the story as it stands, our view is that there exists countless mysteries, scientific anomalies and surprising artifacts that have yet to be discovered and explained.

The goal of Ancient Origins is to highlight recent archaeological discoveries, peer-reviewed academic research and evidence, as well as offering alternative viewpoints and explanations of science, archaeology, mythology, religion and history around the globe.

We’re the only Pop Archaeology site combining scientific research with out-of-the-box perspectives.

By bringing together top experts and authors, this archaeology website explores lost civilizations, examines sacred writings, tours ancient places, investigates ancient discoveries and questions mysterious happenings. Our open community is dedicated to digging into the origins of our species on planet earth, and question wherever the discoveries might take us. We seek to retell the story of our beginnings.
