WebSo the sun returned ten degrees, by which degrees it was gone down. We can only speculate, but it seems likely that once the originator of this legend decided upon an interpretation of 2 Kings 20 that created a "lost" 40 minutes of time, he also decided that the "about a whole day" described in Joshua 10 was a period of exactly 23 hours and 20 minutes so that the two amounts combined would equal exactly one day (even though the length day is actually about 23 hours and 56 minutes). When the Earth rotates 15 degrees on its axis, its just as though the Sun has moved 15 degrees across our sky.

Before the days of affordable wristwatches, people often carried a folding sundial in their pocket ("poke" below), with a small magnetic compass embedded, to show the north direction. New American Standard Bible Sundials have been around for thousands of years, but the first sundials were invented in China in the 13th century. Sundials need to point in the direction of True North, and the style (either a sharp straight edge or thin rod, often located at the edge or tip of the compass needle) needs to be perpendicular to the true north.

This verse was initially read: I will make the shadow on the steps of the dial of Ahaz that marks the sun go ten steps backwards. At the same time it climbed up in the East part of the inclined plane. At 12:00 pm, a very short shadow was cast exactly on the North-South meridian. WebFor an azimuthal (horizontal, vertical, or diagonal) sun dial, the angle is expressed as a number of degrees (e.g., 0 = 360). And, loking on it with lack-lustre eye Here 15N (=15 times N) is an angle in degrees, ranging from 0 to 90, and of course, the afternoon angles are mirror reflections of the morning ones.

Jean Meeus describes the mean sun as follows: Consider a first fictitious Sun travelling along the ecliptic with a constant speed and coinciding with the true sun at the perigee and apogee (when the Earth is in perihelion and aphelion, respectively). Thus, this has allowed scholars to make a connection with the 1885 French astronomer Camille Flammarion, where he published an article about a special sundial in the Observatory of Juvisy in Paris: Flammarion had designed and built a sundial to incline the plane in order to show the retro-gradation of the sun's shadow. They checked the computers going back into the time it was written and found it was close but not close enough. If you are using a telescope, you can use a small mirror to focus the light. Twenty-three hours and 20 minutes in Joshua, plus 40 minutes in Second Kings make the missing day in the universe!" Nonetheless, its factual details are wrong, the scientific processes it describes are dubious, and its premise of a "missing day" depends upon some very selective and questionable intepretations of scripture. This was influenced from, During his experiment, he inclined the board with the gnomon until the gnomon was in such a position that its shadow was cast on the southern part of the plane.

Flammarion also calculated the exact inclination of the gnomon to get a retro-gradation of 10 (according to 2 Kings 20:11), namely 18 north-latitude. It is based on the apparent solar day, the interval between two successive returns of the Sun to the local meridian. When the sun climbs, the shadow of the edge moves down the stairs from step to step. In 2 Kings 20:11, this crucial moment is marked with two verbs: "who brought the shadow back ten steps after it had gone down the stairway of Ahaz.". How much time would this 10 degrees take?
