In early times, astronomy only comprised the observation and predictions of the motions of objects visible to the naked eye. In some locations, such as [[Stonehenge]], early cultures assembled massive artifacts that likely had some astronomical purpose. In addition to their ceremonial uses, these observatories could be employed to determine the seasons, an important factor in knowing when to plant crops, as well as in understanding the length of the year.
