The word "regal" has been derived from the inventor having made a present of the first one to a king, or to kings having had in their establishments special regal-makers. Rigabello, a now unknown instrument which is said to have preceded the organ in Venice, is also quoted as the origin of the name. I have elsewhere (Encyclopædia Britannica, article Pianoforte) suggested that "regal" may have come from "regula," a rule, the idea of gradation being inherent in a key-board. The wooden harmonicon, when made to play by a key-board, was at one time called regal (régale en bois).
PLATE XIII.
PORTABLE ORGAN AND
BIBLE REGAL.
THE Portable Organ (orgue portatif, also nimfali) was a processional instrument slung by a strap over the player's shoulder, so as to allow the bellows at the back of the instrument to be worked by the player's left hand, while the keys were touched with the fingers of the right hand. From the high pitch of the pipes, the limited number of keys, and one hand only being used for touching them, it is possible that only one voice, or part, was played. The same remarks may be made of the early large organs, except that, with them, each key made several pipes of various lengths speak at the same time, so as to give the octave, twelfth, and super-octave, and still higher accordant intervals,—in point of fact, the large organ was, with the exception of the front pipes, a large mixture stop. The positive and portable organs were smaller editions of the principal or front pipe part of the large organ. From Orcagna and Fra Angelico, in the fourteenth century, to D.G. Rossetti and E. Burne Jones, in the nineteenth, the portable organ has been a favourite musical instrument for delineation by the painter of religious subjects, and from the fourteenth to the seventeenth centuries no musical instrument was more in favour in religious establishments. Notwithstanding this fact, I know of only two as now existing, and they are both of late date, being of the seventeenth century. The one, here drawn, belongs to the Museum of the Brussels Conservatoire, while the other, belonging to His Grace the Duke of Athole, is preserved at Blair Athole in Scotland.
The Brussels Portable Organ has twenty-six metal pipes arranged in two rows, and has as many keys, in a compass extending from the first E to the third F above middle C. On the case are engravings upon wood and ivory, representing a youth playing upon a harp while three boys dance, and a woman playing upon a portable organ while a girl and two boys sing. A woodcut of the harp-player is on the title-page of this volume. There is a conventional lion on each key-block. The dimensions are—height, 2 feet 6 inches; width, 2 feet; and depth, 8 inches.
The Bible Regal, drawn in the same Plate, is of the same kind as the beating reed Regal. The pipes which enclose the reeds are so cut down as to practically do little more than cover them. The instrument is so constructed that it can be folded up, and, when closed, looks like a book—whence the name Bible Regal. The key-board, hinged in the middle, is extended for performance. In the instrument drawn it is of four octaves and a fourth compass. The bellows are found by reversing the book cover. The Bible Regal is said to have been invented about the middle of the sixteenth century, by George Voll, an organ-builder of Nuremberg. It is extremely rare; I only know of two, one belonging to Mr. Wyndham Portal of Malshanger, Basingstoke, and this instrument, the property of Mrs. Frederick Pagden and her sister Miss Ferrari.
