According to page 39 of the Historic American Buildngs Survey #532 published in 1987 [PDF via the Library of Congress]:
The sculpture which contributed most sucessfully to the architectural design [of Meridian Hill Park] was the 6′ high armillary sphere. Money for the construction of the sphere was donated by Bertha Noyes, a well-known Washington artist and founder of the Washington Arts Club, in memory of her father and her sister. Paul Manship had constructed a model for an earlier proposal for an armillary sphere. For lack of funds, that sphere was not realized, later when the Noyes Armillary Sphere was constructed by Carl Paul Jennewein, he based his design on the earlier Manship model. The sphere was located in the exedra on axis with the cascade, south of the reflecting pool. This location was proposed by Ferruccio Vitale, and the foundation was designed by Horace W. Peaslee. Congress approved the location within Meridian Hill Park on June 10, 1932, subject to the final approval of its location within the park by the Commission. The sphere, which was of great interest conceptually as well as visually, was described by historian James Goode as follows:
In spite of its seemingly contemporary design, the armillary sphere is, in face, an ancient astrological instrument. The armillary sphere was frequently used in Europe in the seventeenth century to illustrate the Ptolemaic theory of a central earth; it used metal rings which illustrated the nine spheres of the universe. The usual device, a skeleton of the celestial globe with circles arranged into degrees for angle measurement, represents the great circles of the heavens. The latter includes the horizon, meridian, equator, tropics, and polar circle. The Noyes Armillary Sphere includes a series of bronze rings on which are also found the symbols of the zodiac and the hours, given in Roman numerals. A bronze arrow forms the axis, and, in the center, a small winged genie greets the sun. (James M. Goode, The Outdoor Sculpture of Washington, D.C., The Smithsonian Institution Press, 1974)
The armillary sphere suffered serious damage during the late 1960s and was removed for repair. Its whereabouts is presently unknown. The armillary sphere was worked in bronze, and placed on a green granite pedestal. Other significant park embellishments were wrought in iron. For example, at the north end of the park, a wrought-iron fence is decorated with small armillary spheres, reflecting the significance of the Noyes Armillary Sphere.

The Precessional Pentagram of Venus

Successive inferior conjunctions of Venus occur about 1.6 Earth years apart and
create a pattern of precessing pentagrams, due to a near 13:8 orbital resonance
(the Earth orbits nearly 8 times for every 13 orbits of Venus).
Was reading about Transits of Venus and came across this graphic on Wikipedia. What a beautiful celestial design.

The Vicissitude of the Seasons Explained
|| 8/7/2008 || 1:59 pm || Comments Off on The Vicissitude of the Seasons Explained || ||
The other day I posted the Analemma featured on Bowles 1780 Map of the World. Today I am posting another ancillary chart from the map that I thought was interesting. It is called the Vicissitude of the Seasons and it explains the nature of the seasons in a given year. Vicissitude means “a state of being changeable or in flux; the rise and decline of a phenomenon,” and the transcribed chart below is the explains how the Earth slowly goes from Summer to Spring. I’ve been thinking a lot about the seasons lately and I have been working on a new map to address their change over time.
In this Diagram S represent the Sun, A XII BXII the Earth as moving round the Sun in the plane of the Ecliptic, according to the Order of the Signs Aries, Taurus, Gemini, etc. P is the North Pole, C the Arctic Circle, T the Tropic of Cancer, E the Equator, AXIIB the enlightened half of the Earth, where it is Day. BXIIA the darkened half where it is Night and BCA is the boundary of light & darkness. The Earth’s position with respect to the Sun is here shewn at the beginning of Ecliptic and here tis plain that the Earth moves through the Signs Libra, Scorpio, Sagittarius, Capricornus, Aquarius, and Pisces (which is from the 21st of March till the 23 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 23rd of September till the 21st of March, the North Pole is constantly in the Dark and the Northern places have their Nights longer their Days.
Thus, supposing the Circle, L to be parallel of Latitude of London, we perceive that a greater part of it is in the Light than in the Dark from the 21st of March to the 23rd of September and the contrary from the 23rd of September till the 21st of March. On these two days it is just half in the light and half in the dark which shews the Days and Nights to be equally long. On the 21st of June it is most of all in the light, which shews that its days are then at the longest and on the 21st of December it is least of all in the light which shews its days are then at the shortest. The like 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 the opposite part thereof as seen from the Earth.
I think I might use the graphic on the cover of next year’s calendars. Its very similar to the zodiac in Battista Agnese‘s Portolan atlas from 1544 that I used on last year’s calendars.

Astrophotography by Anthony Ayiomamitis – Analemma with the Parthenon
|| 4/1/2008 || 2:28 pm || Comments Off on Astrophotography by Anthony Ayiomamitis – Analemma with the Parthenon || ||
Following up on my antique sundials posting, I just came across this stunning photography by Anthony Ayiomamitis that shows the sun’s yearly orbit seen from a stationary points around various ancient ruins in Greece. The figure 8 design that the sun creates is called an Analemma. It’s a curve representing the angular offset of the sun from its mean position on the celestial sphere as viewed from Earth. The sun’s position in the figure 8 varies by geography and time of year, but when a series of photographs are taken from one location you can see the sun’s relative path through the seasons.
An Updated Astrological Calendar from 1544 – Eastern Hemisphere

About a month ago I made the first version of the map using the Western Hemisphere. At the time I didn’t even think about making a secondary map for the Eastern Hemisphere.
