An ancient jar is a container that has been around for a very long time. However, there are many other words that can be used to describe this type of vessel. For instance, a "vintage urn" or "antique vase" could both be used to describe an ancient jar. Other synonyms may include "archaic pot," "olden jug," or "timeworn amphora." Each of these words evokes a slightly different image in the mind of the reader, but all convey a sense of something old and valuable. Whatever term is used, the concept of an infinitely old container that has seen many years and perhaps many civilizations is always a fascinating one to contemplate.
