| The VICISSITUDE of SEASONS Explained.
In this Diagram S represent the Sun, A XII B XII the Earth as moving round the Sun in the place of the Ecliptic, according to the Order of the Signs Aries, Taurus, Gemini. &c. P is the North Pole, C the Arctic Circle, T the Tropic of Cancer. E the Equator, A XII B the enlightened half of the Earth, where it is Day, B XII A the darkened half where it is Night, and B C A is the boundary of light & darkness. The Earths position with respect to the Sun is here Shown at the beginning of each Sign of the Ecliptic and here 'tis plain that as the Earth moves through the Signs Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces (which is from the 21.st of Match till the 23.d of September) the North Pole P is constantly enlightened, and the Northern Places have their days longer than their Nights But as the Earth proceeds through Aries, Taurus, Gemini, Cancer, Leo, and Virgo (which is from the 23.d of September till the 21.st of March, the North Pole is constantly in the Dark and the Northern places have their Nights longer than their Days. Thus, supposing the Circle, L to be the parallel of Latitude of London, we perceive that a greater part of it is in the Light than in the Dark from the 21.st of March to the 23.d of September and the contrary from the 23.d of September till the 21.st of March On these two days it is just half in the light and half in the dark which shows the Days and Nights to be then equally long. On the 21.st of June it is most of all in the light, which shows that its days are then at the longest, and on the 21.st of December it is least of all in the light which shows that its days are then at the shortest. The like is to be understood of any other place Situated in the Northern Hemisphere, whilst the reverse happens to those in the Southern. But at each Pole, there is only one Day and one Night in the Whole Year. N.B. In whatever part of the Ecliptic the Earth is in, as seen from the Sun, the Sun is then in the opposite part thereof as seen from the Earth. APPLIQUÉS The following appliqués comprise what we believe to be one of the most comprehensive offerings the world over. Periods represented span four centuries, from the Renaissance to Art Deco. |
