1539réf. ST20126Pavia: Giovanni Maria Simonetta 1539. FIRST EDITION Second Issue. 210 x 147 mm. 8 1/2 x 5 3/4". 215 leaves. Restrained 19th century crimson morocco by Trautz-Bauzonnet stamp-signed on front turn-in raised bands spine with gilt text wide turn-ins gilt marbled endpapers all edges marbled and gilt. A small leather label with the year affixed to the spine. With two woodcuts depicting the "phagotus" instrument. Title with an attractive pictorial woodcut border. Printed in black and red. Occasional early ink marginalia; early ink ownership inscription to lower margin of colophon: "Hieronymi Pinzoni Cantoris Cremonensis et praepositi." An Armenian alphabet is inscribed in ink on the rear flyleaf dated March 28 1540. Mortimer 20; Adams I 957; Brunet I 229; Graesse I 59. Spine and edges slightly darkened joints a bit rubbed but without any cracking and the wear skillfully retouched. Only scattered very minor stains and soiling--quite a clean copy internally the leaves very fresh. This volume features one of the strangest combinations of a gravely serious treatise and an oddball curiosity: it comprises a landmark study of linguistics as the first European work concerning Syriac and Armenian--along with 36 other languages; and incongruously it also describes and pictures a contemporaneous musical instrument whose design was sufficiently peculiar to limit its interest to just one person the book's dedicatee. Our work originated when Teseo Ambrogio degli Albonesi 1469-1540 a lawyer scholar and canon of the church of Saint John of the Lateran was tasked with the publication of a Syriac manuscript psalter brought by a Maronite contingent to the Fifth Lateran Council. This was not merely a minor exercise in church outreach: 16th century scholars believed Syriac as a derivative of Aramaic to be the language of Christ. While the present work is of great interest because of its Syriac and Armenian content Ambrogio did not limit himself to those tongues: the text includes in particular short studies of Samaritan Arabic Coptic Cyrillic and Ethiopic. Of these some alphabets are provided in print in types specifically designed by Ambrogio and others are supplied in manuscript in spaces left in the text for that purpose. Ambrogio's sample texts range from simple alphabets to biblical passages to a letter purportedly from the Devil! In addition to the serious work done by our volume the text here deviates to include a fascinating musical surprise. Dedicated to the author's uncle Afranio degle Albonesi ca. 1465 - ca. 1540 a fellow church canon and apparently something of an eccentric the work includes an illustrated section on the "phagotus" a musical instrument of Afranio's own invention. Described by composer John Pickard as a "remarkable monstrosity" the phagotus combined features of the bagpipe and the bassoon. It never gained widespread popularity though not for lack of trying on Afranio's part--he once even performed with it for the duke of Ferrara Alfonso d'Este at a banquet in Mantua. Our copy in a pleasing though unassuming binding by one of the foremost 19th century French workshops was owned during its early history by yet another prominent churchman--Girolamo Pinzoni d. 1554 canon of the church of San Leonardo in Cremona.

Engraved title page frontispiece and 151 PLATES DEPICTING MUSICAL INSTRUMENTS. Front pastedown with bookplates of John Smith Esquire Arthur & Charlotte Vershbow Cia Fornaroli and David R. Godine. Cicognara 1596 citing 148 plates; Brunet I 1086 citing 136 plates; Graesse I 480. A long thin red ruled line to upper cover a few small cuts at edge of front board O1 with insignificant hole trivial loss of text a few light stains isolated faint browning to plates but quite AN EXCELLENT COPY--the leaves extremely fresh and clean and the binding entirely sound and perfectly inoffensive. This is an excellent copy of a sumptuously illustrated Baroque compendium of musical instruments which has been owned by three eminent collectors. A student of Athanasias Kircher the Jesuit scholar Filippo Bonanni also Buonanni 1638-1723 produced works on wide-ranging subjects including anatomy shell-collecting and porcelain lacquer. "Gabinetto Armonico" attempts to catalogue all known musical instruments including a broad range of horns as well as other wind percussion stringed and keyboard instruments not infrequently exotic in appearance and operation from all regions including Florida and the world of Islam. Many of the instruments included here were held in the collection of the Jesuit Collegio Romano where Bonanni was teaching at the time he composed the book; other information was gleaned from various authors and ethnographical reports. The book is organized based on the use for which the music is intended e.g. for festivals funerals battle worship hunting and even navigation. The very attractive illustrations by Flemish-born painter and publisher Arnold van Westerhout 1651-1725 depict the instruments in the hands of their players in their native costumes and environs. While some of the depictions of the ancient and foreign musicians are fanciful the majority of these engravings provide genuine invaluable information on music and musical instruments up to the early 18th century. The musicians are as interesting as the instruments dressed in keeping with the original homeland of the instrument ranging from King David with his harp to fashionable rococo ladies at the keyboards of spinet and cimbalo. Our copy is from the library of Italian ballerina Cia Fornaroli 1888-1954 and her husband Walter Toscanini 1898-1971 a bookseller and choreographer. The couple whose distinguished careers were split between New York and Italy assembled a large collection of works documenting the history of dance in Italy from the Renaissance until the 20th century. The bulk of their library now resides in the Jerome Robbins Dance Division of the New York Public Library for the Performing Arts. Our next notable owners were Arthur 1922-2012 and Charlotte Vershbow 1924-2000 who together built a large collection of prints illuminated manuscripts and printed books. Their collection sold at Christie's New York in a series of four auctions in 2013 the present volume was lot 771. Most recently our copy belonged to American publisher David R. Godine who trained as a printer at Leonard Baskin's Gehenna Press before founding his own publishing firm in 1970. His interest in the art of the book led him to build an extensive library of early printed books with a particular focus on antiquarian illustrated works. Two portions of his collection sold for more than $950000 at Bonham's New York in May 2026. The book is not particularly rare at auction but copies in desirable condition even without the distinguished provenance seen here command substantial prices.

Moulded plastic base has iron weight bolted underneath minor closed crack to the outer fore-edge of the base minor rippling to paint finish at base chipping to plastic bushing at base of Earth & Lunar globes still an exceptional piece in beautiful working condition. The Trippensee Planetarium tellurion or “Elementary Planetarium” has been produced for over 90 years and offers a wonderful astronomical mechanism depicting how day night and the seasons are caused by the movement of the Earth on its axis and its orbit around the Sun. It shows solar and lunar eclipses the motion of Venus in relation to the Sun and the rotation. The globe shows the major continents and cities with no internal political divisions except for the continental United States & Alaska shaded in green on the North American continent. The Tellurion or Tellurium was patented by Alexander Laing originally in 1897 as an educational device to be used in schools. He set up operations in Detroit MI and was later bought out by the Trippensee brothers who introduced their own version with a more reliable bicycle-style chain and gear drive and they sold them steadily. In order to further diversify the company they also built the Eddie Rickenbacker automobile for the E-M-F Company until 1927 when the Everitt Company went under. Trippensee brothers moved later to Saginaw Michigan where they occupied a three-story building at the corner of Cass and South Hamilton staying in business until 1999 when they were purchased by Science First. Their Orrery planetariums were made originally from wood and brass then Bakelite and finally plastics. See: Mark Theobald Coachbuiltcom Trippensee Manufacturing Company Rickenbacker Motors.

Portland OR. First edition of this very rare catalogue detailing the precision balances for mineral assayers manufacturers chemists jewelers and pulp paper makers. Ainsworth 1850-1917 began as a fine watchmaker steam engineer toolmaker and distiller who moved to Denver in 1877 where he initially began working for A.B. Ingols Jewelry. By the 1880s he was operating a jewelry store repairing balance scales for miners and assayers because at the time these were produced in England and required months of turnaround time for them to be shipped back and repaired prior to Ainsworth. Ainsworth developed his own excellent balance as presented in this catalogue which featured a shortened balance beam speeding up the assaying process and were much preferred by Western assay offices and miners. He continued to operate as a watchmaker and clock repairer but by 1895 began producing Brunton’s newly patented Pocket Transit which together with the balances proved to be a very successful combination with his first Catalogues A & B depicting both products issued in 1898. The company would continue to grow after his death and would be purchased by Xavier Science Corporation and now owned by the Denver Instrument Company.
