Women's ornaments consisted of brooches (fibulae), bracelets (armillae), armlets (armillae, bracchialia), ear-rings (inliures), necklaces (monilia), wreaths (coronae) and hair-pins (crinales).
The crowns suspended in churches suggested doubtless the sumptuous pensile luminaries, frequently designated from a very early period as coronae, in which the form of the royal circlet was preserved in much larger proportions, as exemplified by the remarkable corona still to be seen suspended in the cathedral at Aix-laChapelle over the crypt in which the body of Charlemagne was deposited."
On the 18th of May 1866 he made the first spectroscopic examination of a temporary star (Nova Coronae), and found it to be enveloped in blazing hydrogen.
In the first class we have halos, and coronae, or "glories," which encircle the luminary; the second class includes rainbows, fog-bows, mist-halos, anthelia and mountainspectres, whose centres are at the anti-solar point.
Halos are at definite distances (22° and 46 °) from the sun, and are coloured red on the inside, being due to refraction; coronae closely surround the sun at variable distances, and are coloured red on the outside, being due to diffraction.
The city) by the Saracens, Notabile (locale notabile, et insigne coronae regiae, as it is called in a charter by Alphonso, 1428) under the Sicilian rule, and Citta Vecchia (old city) by the knights.
The most interesting members are: a Coronae, a binary consisting of a yellow star of the 6th magnitude, and a bluish star of the 7th magnitude; R Coronae, an irregular variable star; and T Coronae or Nova Coronae, a temporary or new star, first observed in 1866.
In physical science, coronae (or "glories") are the coloured rings frequently seen closely encircling the sun or moon.
Formerly classified by the ancient Greeks with halos, rainbows, &c., under the general group of "meteors," they came to receive considerable attention at the hands of Descartes, Christiaan Huygens, and Sir Isaac Newton; but the correct explanation of coronae was reserved until the beginning of the 19th century, when Thomas Young applied the theories of the diffraction and interference of light to this phenomenon.
Prior to Young, halos and coronae had not been clearly differentiated; they were both regarded as caused by the refraction of light by atmospheric moisture and ice, although observation had shown that important distinctions existed between these phenomena.
It has now been firmly established, both experimentally and mathematically, that coronae are due to diffraction by the minute particles of moisture and dust suspended in the atmosphere, and the radii of the rings depend on the size of the diffracting particles.
These appear ancos differ from halos and coronae inasmuch as their centres are at the anti-solar point; they thus resemble the rainbow.
Of Hale's legal works the only two of importance are his Historia placitorum coronae, or History of the Pleas of the Crown (1736);; and the History of the Common Law of England, with an Analysis of the Law, &c. (1713).
