The tall and slender shapes of these monoliths and their pointed summits have led to their being compared, in popular language, with needles and spindles.[144] The first Greeks who visited the country and found a monumental type so unlike anything they had at home, wished to convey a good idea of it to their compatriots; they accordingly made use of the word ὀβελός, a spindle. It is difficult to understand how their descendants came to prefer ὀβελίσκος, a little spindle.[145] A diminutive hardly seems the right kind of word under the circumstances; an augmentative would, perhaps, have been better. But it was this diminutive that the Romans borrowed from the Greeks of Alexandria and transmitted to the modern world.

This is not the place for an inquiry into the meaning of the obelisk. It may symbolize, as we have often been told, the ray of the sun, or it may be an emblem of Amen-Generator.[146] It seems to be well established, that in the time of the New Empire at least, it was used to write the syllable men, which signified firmness or stability.[147]

The usual situation of the obelisks was in front of the first pylon of the temples. There they stood in couples, one upon each side of the entrance. Those instances where they are found, as at Karnak, surrounded by the buildings of the temple, are easily explained. The two obelisks in the caryatid court were erected during the eighteenth dynasty, at a time when those parts of the temple which lie between the obelisks and the outer wall were not yet in existence. The obelisks of Hatasu, when first erected, were in front of the Temple of Amen as it was left by the early sovereigns of the eighteenth dynasty.

But the obelisk was not the exclusive property of the temples. Some little ones of limestone have been found in the mastabas,[148] and Mariette has described those which formerly stood in front of the royal tombs belonging to the eleventh dynasty, in the Theban necropolis. He has published the inscription which covers the four faces of one of these obelisks, a monolith some ten feet nine inches high.[149] Obelisks seem also to have been employed for the decoration of palaces, as we may conclude from a Theban painting in which one appears before the principal entrance to a villa surrounded with beautiful gardens.[150] Judging by the sizes of people in the same painting, this obelisk must have been about thirteen feet high.

Diodorus speaks of obelisks erected by Sesostris which were 120 cubits, nearly 180 feet, high;[151] and different texts allude to monoliths which were 130, 117, and 114 feet high. We have some difficulty in accepting the first of these figures. The obelisk of Hatasu, at Karnak, which is the tallest known, is 108 feet 10 inches in height.[152] That which is still standing at Matarieh, on the site of the ancient Heliopolis, is only 67 feet 4 inches high. But the fact that it is the oldest of the colossal obelisks of Egypt makes it more interesting than some which surpass it in size (Fig. [167]). It bears the name of Ousourtesen I., of the twelfth dynasty. As a rule, the inscriptions cut upon the four sides of those obelisks which are complete are very insignificant. They consist of little but pompous enumerations of the royal titles.[153]

The two obelisks erected by Rameses II. in front of the first pylon at Luxor were slightly unequal in height. One was 83 feet 4 inches, the other 78 feet 5 inches. To hide this difference to some extent they were set upon bases also of unequal height, and the shorter was placed slightly in advance of its companion, i.e. slightly nearer to the spectator approaching the temple by the dromos.[155] By these means they hoped to make the difference between the two less conspicuous. This difference may have been caused by any slight accident, or by the discovery of a flaw in the granite during the operation of cutting it in the quarry. In dealing with huge blocks like these, such contretemps must have been frequent.

The smaller of the two obelisks was chosen for transport to Paris in 1836. In its present situation on the Place de la Concorde it is separated from the sculptured base upon which it stood at Luxor. The northern and southern faces of that pedestal were each ornamented with four cynocephali adoring the rising sun; the other two had figures of the god Nile presenting offerings to Amen (Fig. [168]).

In order to restore this and other obelisks to the form which they enjoyed in the days of the Pharaohs we should have to give them back their original summits as well as their pedestals. Hittorf has shown that these probably consisted of caps of gilded copper fitted over the pyramidion,[156] in those cases where the latter was not ornamented with carved figures. A curious passage in Abd-al-latif, which has been often cited, proves that the pyramid of Ousourtesen preserved its cap as late as the thirteenth century. "The summit," says the Arab historian, "is covered with a kind of funnel-shaped copper cap, which descends about three cubits from the apex. The weather of so many centuries has made the copper green and rusty, and some of the green has run down the shaft of the obelisk."[157] In the plate attached to his essay, Hittorf gives us a plan and elevation of the pyramidion of the smaller obelisk of Luxor. He shows how its broken and irregular mass implies a metallic covering, a covering whose existence is moreover proved by the groove or rebate, about an inch and a half deep, which runs round the summit of the shaft. His Figs. [3] and [4] show that this groove was carefully polished. His conclusions have failed to find acceptance in some quarters. It has been asserted that the rays of the sun, striking upon such a surface, would be reflected in a dazzling fashion, and that the general effect would have been unsatisfactory. The Egyptians had no such fear. They made lavish use of gold in the decoration of their buildings. According to the inscription which covers the four sides of the pedestal under the obelisk of Hatasu at Karnak, the pyramidion was covered "with pure gold taken from the chiefs of the nations," which seems to imply either a cap of gilded copper, like that of the obelisk at Heliopolis, or a golden sphere upon the very apex. An object of this latter kind is figured in some of the bas-reliefs at Sakkarah. Besides this there is no doubt that the obelisk in question was gilded from head to foot. "We remark, in the first place, that the beds of the hieroglyphs were carefully polished; secondly, that the four faces of the obelisk itself were left comparatively rough, from which we should conclude that the latter alone received this costly embellishment, the hieroglyphs preserving the natural colour of the granite."[158]
