Origin of Constellation

Ian Ridpath:

Maximilian Hell (1720–92), the Hungarian-born director of the Vienna observatory, introduced this constellation in 1789 under the name Psalterium Georgianum, i.e. George’s Psaltery, a psaltery being an ancient form of harp. It was intended to honour King George III of England, patron of William Herschel who had discovered the planet Uranus in 1781. Hell depicted the harp dangling from a ribbon beneath the hooves of Taurus on a chart in Monumenta, Aere Perenniora, Inter Astra Ponenda, a special publication issued to announce this constellation and two others he invented that commemorated William Herschel’s telescopes (see Sources below). Johann Bode adopted Hell’s new constellation on his Uranographia atlas of 1801 but simplified its name to Harpa Georgii. Bode depicted it as a more modern form of harp, dispensed with the suspending ribbon, and angled the harp to fit better between the surrounding constellations (below). This was the representation that became best-known, before it faded from the sky over the following decades.

In 1789, Hell wrote a treatise in which he introduced three new constellations in the sky in honor of Herschel. It first appeared in Latin as Monumenta, Aere Perenniora, Inter Astra Ponenda.

The three constellations that Hell sought to introduce to the heavens are Tubus Herschelii Major (Herschel’s large telescope, held in Castor's left hand), Tubus Herschelii Minor (Herschel’s small telescope, through which Taurus the Bull gazes), and Psalterium Georgianum (George’s Harp, located beneath the legs of Taurus and in front of the mouth of the sea monster Cetus), two in honour of Herschel, and one in honor of King George III. The positions of these constellations are depicted on a total of four star charts. The fourth chart, which provides a general overview of the celestial region, displays not only the constellations but also the position of the planet Uranus, which was discovered by Herschel in 1781.

In the preface, Maximilan Hell explains the introduction of the constellation:

Constellationem hanc formo in Tabula mea III. quae Flamsteedio est 12ma, et in Atlante minore Domini Fortin 24ta, quae eadem comparet in Tabula mea II, et Flamstedii 2da, atque Domini Fortin 14ta; itemque in Tabula mea IV, infra Taurum Zodiacalem, et inter Orionem, atque Cetum, supra Eridanum, e fixis viginti et una, nondum in ullam Constellationem ordinatis, sub figura quidem Psalterii Davidici, decem chordarum, sed nomine, Psalterii Georgiani, insignitam, quod instrumentum Musicum decem chordarum (tanquam Symbolum Decalogi Mosaici) quoniam ab hebraeo Populo ad solas decantandas laudes divinas in Templo Hierosolymitano olim adhibitum sit, mihi (et fortassis etiam Reipublicae astronomicae) maxime congruum videtur, ad Pietatem singularem Christianum Georgii III, qua inter ceteras Virtutes, et dotes Regias maxime eminet, (hoc potissimum Seculo pseudo-philosophico) Symbolice declarandam, et ad Posterorum Astronomorum memoriam perennem, sub hoc Religionis, et Pietatis Symbolo in Coelo adservandam, celebrandamque aptissimum.

Psalterium hoc Georgianum, ut in Tabula mea II, III, et IV exhibetur, componitur e stellis fixis Catalogi Flamsteediani, viginti et una, quarum quatuor sunt quartae magnitudinis, novem quintae, et octo sextae classis.

Figura autem Psalterii ea est, quae respondet descriptionibus S. Hieronymi, S. Augustini, D. Schilte, et aliorum in Kircheri Musurgia relatis: nam ea, quam Kircherus in sua Musurgia Tomi I. Libro II de Musica Hebraeorum exhibet, et quam desumpsisse se asserit ex antiquo Codice Vaticano, quaeque etiam in Opere Encyclopedico: Recueil des Planches par ordre de Materires Tomo IIItio Pl. XIV ex Kirchero deprompt proponitur, descriptionibus S. Hieronymi, et S. Augustini minime congruit: Figura Kircheri similitudinem habet Clypei quadrati, decem chordis instructi: Dominus Schilte autem illud rectius exhibet sub figura Trapezii, et nomine hebraeo Nevel, aut Nablon indicatum, quae vox significat: irganum laudatorium: inde cantus laudatorius vocatur Psalmus, quia ad pulsum Psalterii laudes divinae, et sacrae cantabantur olim ab Hebraeis.

I am designing this constellation in my Plate III, which corresponds to the 12th in Flamsteed’s and the 24th in Mr. Fortin’s celestial atlas; this constellation is also found on my Plate II, and on the 2nd in Flamsteed’s, as well as on the 14th in Mr. Fortin’s star charts, and in my Map IV, located below the zodiacal Taurus, between Orion and the Whale [Cetus], above the river Eridanus, marked by twenty-one fixed stars not yet organized into any constellation, under the figure of the ten-stringed Psaltery of David, but with the name of the Georgian Psaltery. Since this musical instrument of ten strings (as a symbol of the Mosaic Decalogue) was once used by the Hebrew people solely for chanting divine praises in the Temple of Jerusalem, it seems to me (and perhaps also to the astronomical republic) most fitting for symbolically declaring the singular Christian piety of George III, which shines most brightly among his other virtues and royal gifts (especially in this pseudo-philosophical century), and most appropriate for preserving and celebrating his memory for future astronomers under this symbol of religion and piety in the heavens.

This Georgian Psaltery, as it is depicted in my Plates II, III, and IV, comprises 21 stars from Flamsteed’s star catalog, of which four are of the fourth magnitude, nine of the fifth, and eight of the sixth magnitude.

The shape of this Psaltery is exactly that which Saint Augustine and Jerome, as well as Schilte and others cited in Kircher’s Musurgia, have described. For the figure which Kircher himself illustrated in his Musurgia (Book 2, Volume 1) in his description of the music of the Hebrews, which he claims to have drawn from an old Vatican codex, and which was also taken from Kircher for the French Encyclopédie (Recueil des planches, Vol. III, Plate XIV), does not correspond to the descriptions of Saint Jerome and Augustine. Kircher’s figure bears much resemblance to a square shield strung with ten strings; however, Mr. Schilte represents it more correctly in the shape of a trapezium, with the designation Nebel or Nablum, which is a Hebrew word signifying an instrument of songs of praise. Therefore, the song of praise is called a "Psalm", because the Hebrews once sang their hymns of praise during divine service while striking the psaltery.

Identifications

The exact area covered by this image differs between the historical atlases, but it in the area where Taurus, Cetus and Eridanus meet.
