The Foreign Stones were placed in position afterwards. ([See pages 45-49.])
V. Stonehenge and the Summer Solstice
It is a notable fact that the sun rises immediately over the summit of the "Hele Stone," in a line with the axis of Stonehenge on the Summer Solstice.
Sir Norman Lockyer and Mr. Penrose, working on astronomical grounds, fix the date of the circle at 1680 B.C., with a possible error of 200 years on either side.
Much has been said as regards Sun Worship at Stonehenge. The exact use to which the circle was put is at present a matter of conjecture. ([See page 57.])
VI. Stone Circles generally, and Stonehenge
1. Stonehenge is probably the latest, and is certainly the most elaborate, stone circle in England.
2. It is the only one in which the stones are squared, dressed, and provided with lintels or imposts.
3. It is the only circle which contains a "horseshoe" arrangement of stones.
4. Most of the stone circles in the South of England face towards the north-east. Stonehenge is one of these.
