There was the knight of fair-haired Danaë born, Perseus.
Elton's translation of the Shield of Hercules.
Perseus, even amid the stars, must take
Andromeda in chains aetherial!
Mrs. Browning's Paraphrases on Nonnus.
is the French Persée, the Italian Perseo, and the German Perseus, formerly was catalogued as Perseus et Caput Medusae.
He is shown in early illustrations1 as a nude youth wearing the talaria, or winged sandals, with a light scarf thrown around his body, holding in his left hand the Gorgoneion, or head of Medusa-Guberna, the mortal one of the Gorgons, and in his right the ἅρπη, or falx, which he had received from Mercury. Dürer drew him thus, but added a flowing robe, a figuring that Bayer, Argelander, and Heis have followed, as they have, in the main, all of that great artist's constellation figures.
A title popular at one time, and still seen, was the Rescuer, for, according to the story, Perseus, when under obligations to furnish a Gorgon's head to Polydectes, found the Sisters asleep at the Ocean; and, using the shield of p330 Minerva as a mirror, that he might not be petrified by Medusa's glance, cut off her head, which he then utilized in the rescue of Andromeda. Some one has written about this:
In the mirror of his polished shield
Reflected, saw Medusa slumbers take,
And not one serpent by good chance awake;
Then backward an unerring blow he sped,
And from her body lopped at once her head.
Aratos characterized the stellar hero as "stirring up a dust in heaven," either from the fact that his feet are in the celestial road, the Milky Way, or from the haste with which he is going to the rescue of Andromeda; and Manilius, describing his place in the sky, wrote:
Her Perseus joyns, her Foot his Shoulder bears
Proud of the weight, and mixes with her Stars.
His story probably was well known in Greece anterior to the 5th century B.C., for Euripides and Sophocles each wrote a drama based on Andromeda's history; and with them, as with the subsequent Greeks, he was Περσεύς, a word that may be derived from the Hebrew Pārāsh, a Horseman, although Ctesias, in his Περσικά of about 400 B.C., had Parsondas as a stellar name from Babylonia that may be this. Parasiea, current in late Indian astronomy, is only another form of the Greek original.
Ἱππότης, the Horseman, and Profugus, the Flying One, also are titles for these stars.
Classical poets called it Pinnipes, referring to the talaria; Cyllenius, the Hero having been aided by Mercury; Abantiades and Acrisioniades, from his grandfather and father; Inachides, from a still earlier ancestor, the first king of Argos; and Deferens caput Algol, Victor Gorgonei monstri, Gorgonifer, Gorgonisue, and Deferens cathenam, from the association of Perseus with Medusa and the chain of Andromeda.
Alove probably came, by some error in transcription, from Al Ghūl, more correctly applied to the star β; while Bershawish, Fersaus, and Siaush are plainly the Arabians' orthography of the Greek title, the letter P not being found in their alphabet. They, however, commonly called it Hāmil Rāʽs al Ghūl, the Bearer of the Demon's Head, which became Almirazgual in Moorish Spain, and was translated from Ulug Beg as Portans caput larvae, the same being still seen in the German Träger des Medusen Kopf.
The Celeub, Cheleub, and Chelub of the 1515 Almagest, Alfonsine Tables, and Bayer's Uranometria probably are from the Arabic Kullāb, the Hero's weapon, although Grotius and others have referred them to Kalb, a Dog, which would render intelligible the occasional title Canis.
p331 La Lande identified the figure with the Egyptian Khem, and with Mithras of Persia, Herodotus having asserted [II.91] that Perseus, through his and Andromeda's son Perses, gave name to that country and her people, who previously were the Chephenes, as descended from Chepheus, the son of Belus, identified by some with the Cepheus of the sky. The kings of Cappadocia and of Pontus, similarly descended, represented the Hero on their coins.
Cacodaemona was the astrologers' name for this constellation, with special reference to Algol as marking the demon's head; while Schickard, Novidius, and the biblical school generally said that it was David with the head of Goliath; but others of the same kind made of it the Apostle Paul with his Sword and Book. Mrs. Jameson thought that the legend of Perseus and Cetus was the foundation of that of Saint George and the Dragon, one version making this saint to have been born at Lydda, only nine miles from Joppa, the scene of Perseus' exploit.b
The constellation is 28° in length, — one of the most extended in the heavens, — stretching from the upraised hand of Perseus nearly to the Pleiades, and well justifying the epithet περιμήκετος, "very tall," applied to it by Aratos. It offers a field of especial interest to possessors of small telescopes, while even an opera-glass reveals much that is worthy of observation. Argelander gives a list of 81 naked-eye stars, and Heis 136.
The former has suggested that within its boundaries may lie the possible central point of the universe, which Mädler located in the Pleiades and Maxwell Hall in Pisces, — all probably unwarranted conclusions.
δ, ψ, σ, α, γ, η, and others on the figure's right side, form a slight curve, open towards the northeast, that has been called the Segment of Perseus.
Algenib, with the early variations of Algeneb, Elgenab, Genib, Chenib, and Alchemb, is from Al Janb, the Side, its present position on the maps; Chrysococca similarly called it Πλευρά Περσάους.
Another name, Marfak or Mirfak, the Elbow, sometimes written Mirzac, comes from the Arabians' Marfiḳ al Thurayya, thus qualified as being next to the Pleiades to distinguish it from the other elbow. But this may indicate a different representation of Perseus in their day, — a suspicion by the nomenclature of others of his stars, especially of ξ and ο.
Assemani alluded to a title on the Borgian globe, — Mughammid, or Muliammir, al Thurayya, the Concealer of the Pleiades, — which, from its location, may be for this star.
With γ, δ, and others it was the Chinese Tien Yuen, the Heavenly Enclosure.
p332 Algenib never sets in the latitude of New York City, but just touches the horizon at its lower culmination. Its spectrum is of Secchi's second, or Solar, type, and the Potsdam observations indicate that the star is approaching our system at the rate of 6½ miles a second.
the Gorgon's Head, a ghastly sight,
Deformed and dreadful, and a sign of woe.
Bryant's translation of the Iliad.
Algol, the Demon, the Demon Star, and the Blinking Demon, from the Arabians' Ra᾽s al Ghul, the Demon's Head, is said to have been thus called from its rapid and wonderful variations; but I find no evidence of this, and that people probably took the title from Ptolemy. Al Ghul literally signifies a Mischief-maker, and the name still appears in the Ghoul of the Arabian Nights and of our day. It degenerated into the Alove often used some centuries ago for this star.
Ptolemy catalogued it as τῶν ἐν γοργονίῳº ὁ λαμπρός, "the bright one of those in the Gorgon's head," which Al Tizini followed in his Nā᾽ir, for, with π, ρ, and ω, it made up that well-known group, itself being the Gorgonea prima; the Γοργόνιον of Chrysococca, Gorgoneum Caput of Vitruvius [IX.4.2], Caput Gorgonis of Hyginus, and the Gorgonis Ora of Manilius.
With astronomical writers of three centuries ago Algol was Caput Larvae, the Spectre's Head. Hipparchos and Pliny made a separate constellation of the Gorgon stars as the Head of Medusa, this descending almost to our own day, although always connected with Perseus.
The Hebrews knew Algol as Rōsh ha Sāṭān, Satan's Head, Chilmead's Rosch hassatan, the Divels head; but also as Līlīth, Adam's legendary first wife,2 the nocturnal vampire from the lower world that reappeared in the demonology of the Middle Ages as the witch Lilis, one of the characters in Goethe's Walpurgis Nacht.
The Chinese gave it the gruesome title Tseih She, the Piled-up Corpses.
p333 Astrologers of course said that it was the most unfortunate, violent, and dangerous star in the heavens, and it certainly has been one of the best observed, as the most noteworthy variable in the northern sky. It "continues sensibly constant at 2.3 magnitude during 2½ days, then decreases, at first gradually, and afterward with increasing rapidity, to 3.5 magnitude"; its light oscillations occupying about nine hours; its total period being stated as 2 days 20 hours 48 minutes 55 seconds. Al Sufi, a good observer for his day, yet strangely making no allusion to its variability, called it a 2nd‑magnitude; and the phenomenon was first scientifically noted by Montanari during several years preceding 1672. This was confirmed by Maraldi's observations of 1694, and, later, by those of the Saxon farmer Palitsch,3 but its approximate period seems to have been first announced by Goodricke in 1782, who even then advanced the theory of a dark companion revolving around it with immense velocity, which periodically cut off its light. This, reaffirmed by Pickering in 1880, was made certain by the spectroscope in the hands of Vogel of Potsdam in 1889. Chandler thinks that there must exist another invisible body larger than either Algol or its companion, around which both revolve in a period of 130 years; but Tisserand has shown that the phenomenon on which Chandler bases this opinion can be explained in a different and simpler way. Its name is used for the type indicating short-period variables whose changes may be explained by this theory of "eclipses." Of these seventeen are now known.
Although classed among the white stars with a Sirian spectrum, Al Sufi wrote of it as red, which Schmidt confirmed as seen by him at Athens for a short time in 1841. It seems to be approaching us at the rate of about a mile a second; and is estimated as a little more than a million miles in diameter.
When on the meridian Algol is almost exactly in the zenith of New York City. This is at nine o'clock in the evening of the 23d of December.
In China this, with the 4th‑magnitude ν and some others, was Keuen She.
It has been suspected of variation in color as well as in light. The components are about 9ʺ apart, at a position angle of 10°, and form an interesting object for a four-inch telescope.
is unnamed except in China, where, with γ, it was Tien Chuen, Heaven's Ship. But it is noticeable in having three small stars on one side nearly in line, and one on the other, forming a miniature representation of Jupiter and his satellites. The components are 28ʺ apart, at a position angle of 300°.
λ and μ, 4th- to 5th‑magnitude stars, were Tseih Shwuy, Piled-up Waters.
ξ, a 4½‑magnitude, is the Menkib of Burritt, from Mankib al Thurayya, the Shoulder of — i.e. next to — the Pleiades in the Arabian figure, although on modern charts it marks the left ankle.
π, a double star of 4th and 9th magnitudes, is Ati and Atik, from the word Al ʽĀtiḳ found on the Borgian globe, at the space between the shoulders, and applied to it by Ulug Beg; but it is now located near the left foot.
π, a 4½‑magnitude, was Gorgonea secunda; and ρ, a variable from 3.4 to 4.2, orange in color, was Gorgonea tertia.
τ, a 4½‑magnitude, with others in the constellation, was known by the Chinese as Ta Ling, the Great Mound.
marking the tip of the weapon in Perseus' hand, bears many titles with Bayer, all referring to its location; but none of these — indeed, no name at all — is seen in modern lists. Bayer wrote of them:
In falce adamanthinā trium praecedens. Falx dicitur & curvus Harpes, Gladius falcatus, & incurvus, Arab. Nembus, Maroni Ensis falcatus, & curvus Saturni dens.
The "Arab." would seem erroneous, for Nembus is neither Arabic nor Latin, and if intended for Nimbus, is equally wrong, as there is no suspicion of nebulosity about the star. Curvus Saturni dens was Vergil's designation in the Georgics [II.406] for a "pruning-hook," and the equivalent of Falx and Ἅρπη, so well known in connection with Perseus.
χ, a multiple star, and the little h mark two clusters noticeable with the naked eye, Nos. 884 and 869 of the New General Catalogue, 30′ and 15′ in diameter, almost connected, and apparently a protuberant part of the Milky Way. They were the Arabians' Miʽṣam al Thurayya, the Wrist of — i.e. next to — the Pleiades.
Hipparchos seems to have been the first to record them, which he did as νεφελοειδής, a "cloudy spot"; Ptolemy, as συστροφή, a "dense mass"; and subsequent astronomers down to Galileo's day similarly considered them nebulous. The Alfonsine Tables said, revolutio nebulosa, and the Almagest of 1551, girus ille in capulo ensis, this girus — correctly gyrus — signifying a circle. They seem strangely to have escaped the notice of astrologers, p335 who, as a rule, devoted much attention to clusters as harmful objects which portended accidents to sight and blindness.
In China they were Foo Shay.
These stars and clusters are now known as the Sword Hand of Perseus, i, g, φ, and υ marking the outstretched sword. In small telescopes the twin clusters form one of the most beautiful objects within their reach.
Between χ and η lies the diverging point of the Perseids, the prominent meteor stream visible from the 19th of July to the 17th of August, its maximum occurring about the 10th of the latter month and continuing several days. These appear in the early part of the night, at an elevation of from fifty-six to seventy miles, moving with moderate speed and leaving streaks of yellow light; the radiant advancing nearly 30° eastward during their period of visibility. Schiaparelli found their orbit coincident with that of Tuttle's comet, III of 1862. The Perseids were recorded as far back as 811, seven appearances being mentioned down to 841, and they are supposed to have been members of the solar system for thousands of years, although now, perhaps, steadily decreasing in number. Dante may have made reference to them in the Purgatorio [V.37‑39]:
Vapors enkindled saw I ne'er so swiftly
At early nightfall cleave the air serene,
Nor, at the set of sun, the clouds of August;
ω, of the 5th magnitude, was Gorgonea quarta.
1 Tintoretto's celebrated painting of the hero's exploit now hangs in the Hermitage Gallery of Saint Petersburg.
2 We are indebted to the Talmudists for this story, which probably originated in Babylonia; and they added that, after Adam had separated from Līlīth and their demon children, Eve was created for him. Our Authorized Version renders the original word, in Isaiah xxxiv.14, by "screech owl"; the Revised Version, by "night-monster"; Cheyne adopts the Hebrew Lilith in the Polychrome Bible; and Luther's Bible had Kobold, but this corresponded to the Scottish Brownie and the English "Robin Goodfellow," — Shakespeare's "Puck." Saint Jerome's Vulgate translated it "Lamia," the Greek and Roman title for the fabled woman, beautiful above, but a serpent below, that Keats reproduced in his Lamia.
3 Palitsch also was famous for his discovery of Halley's comet on Christmas night, 1758.
4 It is in the church of this Saint Laurence at Upton that the remains of Sir William Herschel lie buried, and over them is the fitting inscription:
Coelorum perrupit claustra.
a Cacodaemon (Greek κακοδαίμων): "evil spirit".
b For the well-documented and rather extensive connections between Perseus and St. George, mentioned by Sir Thomas Browne (Pseud. Ep. V.17) — in 1646, long before Mrs. Jameson — as well as the Lydda-Joppa locale, see Ch. Clermont-Ganneau, Horus et Saint Georges, IV.
c Not only in the faraway Middle Ages nor only in France! In Italy the lagrime di S. Lorenzo are still associated and celebrated with the saint's feast, as for example on the mountain of Ponze di Trevi in Umbria; an ideal place from which to see them, far from smog and light pollution.
