Bootes Seasons Marker

Deciphering rock art from Israel,

Rock art preserved ancient knowledge in the same way that books do today. The many rock art compiled together created a visual book of the past that also documented the ancient thoughts. For example, we learn that the time of the year was extracted from the cyclical arrival of stars.  The rock art presented here is a fine example of using astronomy to determine the seasons.

Bootes Constellation 

The name Bootes, of Greek origin, implies a plowman or herder, since he follows the Ursa Major and Ursa Minor constellations as they circle endlessly the pole star, see Fig.1. The main star of the Bootes constellation, Arcturus, shines with a golden yellow hue in spring and summer and is easily recognizable in the night sky.

Ancient navigators and farmers knew Arcturus; his rising marked the Spring Equinox and his setting marked the Fall Equinox. In his poem, Works and Days, Hesiod (around 700 BC) reminds the farmers to count sixty days from the summer solstice to watch the rise of Arcturus 

‘Now, when Zeus has brought to completion sixty more winter days after the sun has turned in his course, the star Arcturus, leaving behind the sacred stream of the ocean, first begins to rise and shine at the edges of the evening. After him, the treble-crying swallow, Pandion’s daughter, comes into the sight of men when spring is just at the beginning. Be there before her. Prune your vines’.

Fig.2 of the Negev rock art shows us an example of employing star knowledge. In this rock art, we see three similar figures in a circle like an arrangement.   The repeated image shows the Bootes constellation as it appears in the sky at different seasons. It is recognizable by its kite-like body shape, the shiny star Arcturus, the extended hands over its head, and the dagger.

The different figure positions, in Fig.2, show the constellation Bootes rising pose for each season. In spring, it rises bouncing back to life after its demise in fall, in summer it stands upright, and in autumn, it vanishes from the sky as seen by the constellation falling pose, which symbolizes death. The ibex (Fertility God Orion constellation see,  Ibex and Rock art) takes Boote’s place as a symbol of the current fertile season, the winter,  which lasts until Bootes reappears in spring.


The glowing stars paved the way for the ancients to explain nature’s behavior.   Their cyclical behavior made it possible to create calendars that regulated life and therefore were quickly adopted by all cultures. Boote’s unique shape tracked easily and its appearance and disappearance marked the changing seasons from spring to autumn. His unique star shape turned him into a warrior fighting the hidden nature forces.  Not surprisingly, the belief in the star’s power is still alive in modern Astrology circles.
