National Museum of Serbia has this to say about these artifacts:
"Prosopomorphic lids are common in the entire territory of the Vinča culture and are all very similar. Most are of cylindrical shape and have prominent horn-like lugs, a molded nose, conspicuously marked eyes and varied decoration. This type of vessels represents a specific form of Vinča ware and had a double function. It was used as a cover for amphorae with a cylindrical neck. Its other and much more important function was to protect the contents of the vessel from evil spells and unknown powers. The most expressive details on the face are the eyes, which attract particular attention. They are associated with the so-called "mystical eyes", to which special significance was attached. It is a widespread belief that the eyes are "the mirror of the human soul", and that they can also be wicked and capable of casting evil spells. They often have the power to avert negative magic power from the individual or the community, so that they assume an apotropaic function. In addition, the eyes possess the power of constant observation, wakefulness, control, surveillance of the behavior of people, and in this way they have an influence on their magic beliefs and religion. Finally, prosopomorphic lids may represent a mask which has the magic power to protect the ordinary human being or the priest-wizard from the unbounded energy of the deity before which he appears. As such, they cannot be considered in isolation from the other Vinča sculptures, altars and cult objects, for they are all associated with the religious rituals and beliefs of prehistoric communities."
Basically no one knows what these things are and what they represent. This is how they were used:
This next picture is a picture of the Eurasian eagle-owl...
Do you see any similarity?
Owls are one of the oldest species of vertebrate animal in existence, fossils have been found dating back 60 million years, showing the bird to have changed very little in that time.
Throughout the history of mankind, the owl has featured significantly in mythology & folklore. They are one of the few birds that have been found in prehistoric cave paintings. This is an engraving of an owl from the the Chauvet-Pont-d'Arc Cave in southern France. The cave has the earliest known and best preserved figurative cave paintings. The dates of the paintings have been a matter of dispute but a study published in 2012 supports placing the art in the Aurignacian period, approximately 32,000–30,000 BP.
The Owl has been engraved by using a tool on the soft surface of the rock, once this surface had been prepared and scraped clean.
The intriguing aspect of the Owl is that it is depicted with its head seen from the front but its body from the back. It may well be the earliest representation of the birds unique ability to turn its head through 180 degrees, an ability which many cultures associate with supernatural powers.
Owls have been both revered & feared throughout many civilizations from ancient to more recent times. It is probably their ability to see in the darkness that inspired people to associate owls with both prophetic wisdom and particularly the visions of doom and death. In most parts of the world the owl cry heard in or near a home usually meant impending death, sickness, or other misfortune. They are also widely believed to represent the souls of people who have died or that they carry the souls of people to the underworld.
So, what do you think? Are the above lids representations of owl heads? And if so, what did these lids cover? What did Vinčans associate owls with?
