chance to make good their flight, unless the Israelites were enabled to pursue them with unusual speed? And if the Israelites were so enabled, then no further miracle is required; for them the sun would have "hasted not to go down about a whole day."

Leaving the question as to whether the sun appeared to stand still through the temporary arrest of the earth's rotation, or through some exaltation of the physical powers of the Israelites, it seems clear, from the foregoing analysis of the narrative, that both the prose account and the poem were written by eye-witnesses, who recorded what they had themselves seen and heard whilst every detail was fresh in their memory. Simple as the astronomical references are, they are very stringent, and can only have been supplied by those who were actually present.

Nothing can be more unlike poetic hyperbole than the sum of actual miles marched to the men who trod them; and these very concrete miles were the gauge of the lapse of time. For just as "nail," and "span," and "foot," and "cubit," and "pace" were the early measures of small distance, so the average day's march was the early measure of long distance. The human frame, in its proportions and in its abilities, is sufficiently uniform to have furnished the primitive standards of length. But the relation established between time and distance as in the case of a day's march, works either way, and is employed in either direction, even at the present day. When the Israelites at the end of their campaign returned from Makkedah to Gibeon, and found the march, though wholly unobstructed, was still a heavy performance for the whole of a long day, what could they think, how could they express themselves, concerning that same march made between noon and sundown? Whatever construction we put upon the incident, whatever explanation we may offer for it, to all the men of Israel, judging the events of the afternoon by the only standard within their reach, the eminently practical standard of the miles they had marched, the only conclusion at which they could arrive was the one they so justly drew—

"The sun stayed in the midst of heaven and hasted not to go down about a whole day. And there was no day like that before it or after it, that the Lord hearkened unto the voice of a man: for the Lord fought for Israel."

CHAPTER II THE DIAL OF AHAZ

The second astronomical marvel recorded in the Scripture narrative is the going back of the shadow on the dial of Ahaz, at the time of Hezekiah's recovery, from his dangerous illness.

It was shortly after the deliverance of the kingdom of Judah from the danger threatened it by Sennacherib king of Assyria, that Hezekiah fell "sick unto death." But in answer to his prayer, Isaiah was sent to tell him—

"Thus saith the Lord, the God of David thy father, I have heard thy prayer, I have seen thy tears: behold, I will heal thee: on the third day thou shalt go up unto the house of the Lord. And I will add unto thy days fifteen years; and I will deliver thee and this city out of the hand of the king of Assyria; and I will defend this city for Mine own sake, and for My servant David's sake. And Isaiah said, Take a lump of figs. And they took and laid it on the boil, and he recovered. And Hezekiah said unto Isaiah, What shall be the sign that the Lord will heal me, and that I shall go up into the house of the Lord the third day? And Isaiah said, This sign shalt thou have of the Lord, that the Lord will do the thing that He hath spoken: shall the shadow go forward ten degrees, or go back ten degrees? And Hezekiah answered, It is a light thing for the shadow to go down ten degrees: nay, but let the shadow return backward ten degrees. And Isaiah the prophet cried unto the Lord: and He brought the shadow ten degrees backward, by which it had gone down in the dial of Ahaz."

The narrative in the Book of Isaiah gives the concluding words in the form—

"So the sun returned ten degrees, by which degrees it was gone down."

The narrative is complete as a record of the healing of king Hezekiah and of the sign given to him to assure him that he should recover; complete for all the ordinary purposes of a narrative, and for readers in general. But for any purpose of astronomical analysis the narrative is deficient, and it must be frankly confessed that it does not lie within the power of astronomy to make any use of it.

It has been generally assumed that it was an actual sundial upon which this sign was seen. We do not know how far back the art of dialling goes. The simplest form of dial is an obelisk on a flat pavement, but it has the very important drawback that the graduation is different for different times of the year. In a properly constructed dial the edge of the style casting the shadow should be made parallel to the axis of the earth. Consequently a dial for one latitude is not available without alteration when transferred to another latitude. Some fine types of dials on a large scale exist in the observatories built by Jai Singh. The first of these—that at Delhi—was probably completed about 1710 a.d. They are, therefore, quite modern, but afford good illustrations of the type of structure which we can readily conceive of as having been built in what has been termed the Stone Age of astronomy. The principal of these buildings, the Samrat Yantra, is a long staircase in the meridian leading up to nothing, the shadow falling on to a great semicircular arc which it crosses. The slope of the staircase is, of course, parallel to the earth's axis.

It has been suggested that if such a dial were erected at Jerusalem, and the style were that for a tropical latitude, at certain times of the year the shadow would appear to go backward for a short time. Others, again, have suggested that if a small portable dial were tilted the same phenomenon would show itself. It is, of course, evident that no such suggestion at all accords with the narrative. Hezekiah was now in the fourteenth year of his reign, the dial—if dial it was—was made by his father, and the "miracle" would have been reproduced day by day for a considerable part of each year, and after the event it would have been apparent to every one that the "miracle" continued to be reproduced. If this had been the case, it would say very little for the astronomical science of the wise men of Merodach-Baladan that he should have sent all the way from Babylon to Jerusalem "to inquire of the wonder that was done in the land" if the wonder was nothing more than a wrongly mounted dial.

Others have hazarded the extreme hypothesis, that there might have been an earthquake at the time which dipped the dial in the proper direction, and then restored it to its proper place; presumably, of course, without doing harm to Jerusalem, or any of its buildings, and passing unnoticed by both king and people.

A much more ingenious theory than any of those was communicated by the late J. W. Bosanquet to the Royal Asiatic Society in 1854. An eclipse of the sun took place on January 11, 689 b.c. It was an annular eclipse in Asia Minor, and a very large partial eclipse at Jerusalem, the greatest phase taking place nearly at local noon. Mr. Bosanquet considers that the effect of the partial eclipse would be to practically shift the centre of the bright body casting the shadow. At the beginning of the annular phase, the part of the sun uncovered would be a crescent in a nearly vertical position; at mid eclipse the crescent would be in a horizontal position; at the end of the annular phase the crescent would again be in a vertical position; so that the exposed part of the sun would appear to move down and up in the sky over a very small distance. It is extremely doubtful whether any perceptible effect could be so produced on the shadow, and one wholly fails to understand why the eclipse itself should not have been given as the sign, and why neither the king nor the people seem to have noticed that it was in progress. It is, however, sufficient to say that modern chronology shows that Hezekiah died ten years before the eclipse in question, so that it fell a quarter of a century too late for the purpose, and no other eclipse is available to take its place during the lifetime of Hezekiah.

But there is no reason to think that the word rendered in our Authorized Version as "dial" was a sundial at all. The word translated "dial" is the same which is also rendered "degrees" in the A.V. and "steps" in the R.V., as is shown in the margin of the latter. It occurs in the prophecy of Amos, where it is rendered "stories" or "ascensions." It means an "ascent," a "going up," a "step." Thus king Solomon's throne had six steps, and there are fifteen Psalms (cxx.-cxxxiv.)—that are called "songs of degrees," that is "songs of steps."

We do not know how the staircase of Ahaz faced, but we can form some rough idea from the known positions of the Temple and of the city of David, and one or two little hints given us in the narrative itself. It will be noted that Hezekiah uses the movement of the shadow downward, as equivalent to its going forward. The going forward of course meant its ordinary direction of motion at that time of day; so the return of the shadow backward meant that the shadow went up ten steps, for in the Book of Isaiah it speaks of the sun returning "ten degrees by which degrees it was gone down." It was therefore in the afternoon, and the sun was declining, when the sign took place. It is clear, therefore, that the staircase was so placed that the shadow went down the stairs as the sun declined in the sky. The staircase, therefore, probably faced east or north-east, as it would naturally do if it led from the palace towards the Temple. No doubt there was a causeway at the foot of this staircase, and a corresponding ascent up the Temple hill on the opposite side of the valley.

We can now conjecturally reproduce the circumstances. It was afternoon, and the palace had already cast the upper steps of the staircase into shadow. The sick king, looking longingly towards the Temple, could see the lower steps still gleaming in the bright Judean sunshine. It was natural therefore for him to say, when the prophet Isaiah offered him his choice of a sign, "Shall the shadow go forward ten steps, or back ten steps?" that it was "a light thing for the shadow to go down ten steps: nay, but let the shadow return backward ten steps." It would be quite obvious to him that a small cloud, suitably placed, might throw ten additional steps into shadow.

It will be seen that we are left with several details undetermined. For the staircase, wherever constructed, was probably not meant to act as a sundial, and was only so used because it chanced to have some rough suitability for
