Egyptian Astronomy: 2. The Causeways of the Pyramids

Causeways and their Orientations

Causeways, now much in ruins, were once covered walkways leading from the east to the temples of the pyramids. They were beautifully decorated with star patterns. We found them to be of interest and possible relevance to the Kanayama Calendar because of their orientations.

From northernmost pyramid, the three pyramid causeways point in the following directions. See Fig. 61.

Khufu’s:  14 degrees north of east

Khafre’s:  14 degrees south of east

Menkaure’s:  due east

What is the significance of these orientations?

Causeways and Cross-quarters

At the 30 degrees north latitude of Giza, the summer solstice direction is 28 degrees north of east, while the winter solstice direction is 28 degrees south of east. The 14 degree alignments means that the causeways point in directions of the summer and winter cross-quarters of the sun’s path. See Fig. 65 and


Cross-quarter Solar Observations?

Were the Egyptian causeways used for making solar observations on cross-quarter dates? We seriously doubt it. The ancient Egyptians used their knowledge of astronomy and built the causeways along with the other monuments. Then they covered the causeways with ceilings for those walking those corridors. Those ceilings would not allow the use of causeways for solar observations.

Winter Causeway

Yet, the causeways symbolized the directions to important astronomical phenomena at the time of Zep Tepi. The winter causeway of Khafre points to the sun rising at the breast of Leo, while the view of Leo matches the head and shoulders of the Sphinx. Again, the sky is imaged on the earth. See Fig. 66.

Summer Causeway

What of the other causeway? The authors of The Message of the Sphinx do not comment on its astronomical nor ritual meaning. However, the figures in the book show that this is the direction to the Virgo constellation at The First Time. Virgo may be the symbol of Isis, consort of Osiris. The reason that the causeways can point to two adjacent constellations (usually 30 degrees apart) is that the solstitial directions are nearly 30 degrees (actually 28 degrees). The two cross-quarter directions are separated by nearly 30 degrees and point to Leo and Virgo.

The Great Year

The ancient Egyptians were familiar with the Great Year of 25,920 years due to the precession of the axis of the earth. Their Zep Tepi occured half a Great Year ago from our own time, around 10,500 BCE.  See Fig. 74. The Sphinx and then the Giza pyramids were constructed in a magnificent plan to commemorate Zep Tepi. They form one of the most splendid monuments on earth. No doubt elaborate ceremonies honored the First Time and the connection between sky and earth for vast periods of time.

Orion is now nearly at the “top” of its great cycle. Is it not fitting that these discoveries are being made half a Great Cycle after the First Time of Zep Tepi?

Concluding Remarks about Egyptian and Kanayama Monuments

The Egyptian monuments are an intricate systems design. So are the Kanayama Megaliths, with their three coordinated sites and dozens of observations which together produce the super-accurate Kanayama Solar Calendar. These two systems have different purposes, yet both are remarkable achievements of the human consciousness that conceived and executed the plans.


Egyptian Astronomy: 1. The Sphinx and Zep Tepi

Monuments of Ancient Egypt

We, at Kanayama Megaliths, have been studying the Egyptian monuments in order to understand their megalithic calendar. The Message of the Sphinx has been an excellent resource. 

Ref:  The Message of the Sphinx by Graham Hancock and Robert Bauval, 1996.

This book shows that the Great Sphinx and the Giza pyramids are a system and a monument to Zep Tepi, The First Time. The authors explain what it means in astronomical terms. Sifting through physical evidence and running astronomical software to visualize ancient skies, they came to stunning conclusions. We will refer to figures from their book.

Giza Pyramids

All Giza Pyramids

Giza Pyramids, Wikipedia

Please keep in mind that the great Giza pyramids were never intended to serve as tombs. They were places of high initiation, of preparation of the pharaoh into immortality when his soul after death joins the stars in the sky.

Zep Tepi

Zep Tepi, The First Time, is often refered to in the Egyptian texts, “the remote epoch when the gods were believed to have come to earth and established their kingdom in Egypt.” (p. 79). In the authors’ view, the First Time refers to the time long ago when Orion was at its lowest meridian point, just above the horizon toward the south. Now Orion appears quite high in the sky although it is still a southern constellation. The apparent movement of Orion in the sky is due to the earth’s precession cycle which is of duration 25,920 years. See Fig. 58 in the book.

Hancock and Bauval determined that this took place around 10,500 BCE. The leonine Sphinx may have been built at that time to face its image, the stellar constellation Leo, when the sun rose on vernal equinox morning.

As for the Giza pyramids, they were built about eight millenia later. However, they follow a plan that is connected to and consistent with the Sphinx. Thus there is a Giza system or a Giza Plan.

Giza Ground Plan


Orion Constellation

Hancock and Bauval show that the ground plan of the three great pyramids matches the pattern of three stars in Orion’s belt, while the Nile River represents the Milky Way galaxy in the sky. As the axiom goes, “As Above, so Below.” Orion is the stellar symbol of Osiris; Sirius is the symbol of his consort Isis.

Astronomical Conjunctions of Giza

The significant conjunctions of the Giza system at the time of Zep Tepi, 10,500 BCE are (see Fig. 30):

* Vernal equinox at dawn,

– The sun rises in Leo (conjunction of sun and Leo), and the Sphinx gazes at this conjunction in the east.

– At the same moment, Orion transits the meridian. This is mirrored by the three great pyramids.

* Summer solstice at dawn,

– The Milky Way is nearly vertical in the eastern sky.

– Orion transits the meridian 3.5 hours later. See Fig. 36.

* Conjunction of Sirius with the horizon:  Around 11,500 to 10,500 BCE Sirius appears for the first time in the sky, just above the horizon almost due south; it is seen only as far north as the Giza latitude of 30 degrees north. Sirius could not be seen from here before this time period;  the proper motion of Sirius in space has brought it into view.


Kanayama Calendar and Astronomical Cross-Quarter Dates



The Kanayama solar calendar features solar observations made on certain dates of the year. These are dates that we, at Kanayama Megaliths, refer to in Japanese as yontobunand in American English as half-angle dates.

The astronomical cross-quarter dates are those days of the year when the sun’s declination angle is midway between its summer solstice or winter solstice declination and the zero angle at equinox time. Notice that the dates come in pairs. The winter pair occur when the declination is half of the approximately -23.5 degrees. The summer pair occur when the declination is half of +23.5 degrees. These dates are fixed all around the planet, independent of latitude or longitude.

The astronomical cross-quarter dates given by Universe Today (see link below)

are 10/24, 2/18, 4/21, 8/22 for 2015. They agree to within one day or two with Kanayama.

We, at Kanayama Megaliths, have hesitated to use the term “astronomical cross-quarter dates”(although it is correct) because, in Europe and in America, people think it means the pagan holidays called “cross-quarter holidays” such as Lammas and Halloween which fall approximately mid-way (about 45 days) after the solstices and the equinoxes.


If you have been following our posts, you know that the Kanayama half-angle dates occur in pairs. The winter pair  are about 60 days before and after the winter solstice. The summer pair are about 60 days before and after the summer solstice. For reference we list them here.

Winter:  10/23 and 2/19.     Summer:  4/22 and 8/20

The Kanayama Megalithic Solar Calendar makes full use of these two pairs of dates. On those days of the year, special observations of sunlight are made. They help to pinpoint the exact dates of summer solstice and winter solstice, which is what a calendar is meant to do. This is, to a large extent, why the Kanayama Calendar is so accurate.
