This contribution examines several machines and instruments that use fireworks to create light drawings in the sky. Since time immemorial, and even today, numerous publications focus on this issue, including different kinds of Italian handbooks written by chemical artillery experts who focus on these pyrotechnical problems. In the late eighteenth century several important hand- books used extremely accurate and precise graphic representations to explain the composition of these unique mechanisms, the techniques used to create, and the ensuing results. This contribution reviews the most important images and drawings in one of these handbooks written in 1785 by John Maskall and entitled “Artificial fireworks”. It also focuses on the design of pyrotechnical devices.
Through a lasting period of time between XVI and the beginnings of XX century the arrangement of Catherine wheels and firework displays during important religious and secular festivals represented for the inhabitants of Rome one of the most popular and awaited events of the tradition. The planning and the construction of the pyrotechnical mechanisms in the most suggestive places of the town (St. Peter's Basilica, the Janiculum Hill, the Coliseum, Castel S. Angelo, Piazza del Popolo with the public gardens of Pincio) kept busy a wide and heterogeneous group of makers including architects, engineers, craftsmen, painters, sculptors and skilful stokers. The tradition of the so called Girandola Romana can be considered a form of total art show in which the urban landscape was transformed by a series of ephemeral architectures, made of different materials (wood, iron, papier-mache and cloth) that were juxtaposed to the monuments' facades. The contribution aims to analyze some of these impressive pyrotechnic costructions through their different representations: these drawings reproduce in a very sophisticated way the ephemeral scenographies of festivals wisely using methods and techniques of representation. The attention will also be turned to the design strategies of architects and engineers involved in the construction of these phantasmagoric structures. The ability of the designer is essential to understand the functioning of these mechanisms and also to retrace the creative process to the base of a pyrotechnical display with its games of colours and lights.
In the seventeenth century, the word fireworks occurred in British newspapers mainly in the context of battle. Fireworks collocated in this semantic field with such nouns as cannons, 1 ordnance, mortar-pieces, 2 granadoes, guns, 3 fire pikes, fire hogs, cartrages of pouder, shot, fowlers, demicannons, falcons, demiculverins, sacres, minions, murtherers, 4 bombs, and carcases. 5 On the relatively few occasions that the word fireworks occurred in the context of entertainment spectacle, it was on the occasion of some public celebration such as the birth of royalty. On such occasions, the word fireworks then collocated with far fewer nouns, such as bonfires, 6 pitch-barrels, 7 rockets, 8 bells, and guns. 9 On the scant occasions that such fireworks were itemized, the nouns used had all long been present in the English language: rockets, runners on the line, wheels, reporters, and Hercules club. 10 This pattern changed around the turn of the century. From 1700 onwards, British newspapers included the word fireworks mainly in the context of entertainment spectacle, and, as the century wore on, the position of the word in the newspaper shifted

Zu den bedeutendsten Stücken in der Sammlung des Historischen Vereins von Oberbayern gehört das einzige bekannte altkolorierte Exemplar von Sebastian Behams Holzschnitt »Manöver zu Ehren Kaiser Karls V. anlässlich dessen München-Besuchs 1530«. Das von Niklas Meldemann gedruckte Blatt wurde 1860 im Rahmen der Gesamttagung der Geschichtsvereine an den Verein geschenkt und jahrzehntelang in den Vereinsräumen ausgestellt. Durch den vorliegenden Beitrag wird es aus seiner zwischenzeitlichen Versenkung wieder hervorgeholt und-im Vergleich mit eindrucksvollen Abbildungen verschiedener Siegesfeiern-als herausragende Dokumentation eines Huldigungsevents und einer militärischen Darbietung der Zeit vorgestellt. Neben der Darstellung militärischer Macht wurden auf Blättern dieser Art stets die technischen Errungenschaften der Zeit, darunter die verschiedenen Formen der Pyrotechnik, mit Freude am Detail illustriert. Auch die besiegten »Feinde«-insbesondere die einfach darzustellenden Türken-wurden gerne vorgeführt. Unter vergleichbaren Siegesfeier-Darstellungen nimmt der Beham-Holzschnitt des Historischen Vereins aufgrund seiner außergewöhnlichen Größe, seines theatralischen Aufbaus und vor allem seiner Farbigkeit eine Sonderstellung ein. Jüngst auf Anregung der Autorin Alison Stewart durchgeführte Analysen der eingesetzten Farben bestätigten, dass die eindrucksvolle Kolorierung-mit der Ausnahme einer kleinen Retusche-aus der Zeit des Drucks stammt. Die reichhaltige Farbpalette beinhaltet Pigmente, die zu dieser Zeit in der Malerei weit verbreitet waren. Die Farben kamen aus den gleichen Quellen, die auch die Chemikalien für das abgebildete Schießpulver und die Pyrotechnik lieferten-den deutschen Apotheken des 16. Jahrhunderts. Dieser Beitrag ist das Ergebnis einer Zusammenarbeit von Alison G. Stewart und Nicole Roberts. Letztere schrieb den Abschnitt »Farbanalyse« am Ende des Aufsatzes. A little studied Einblattdruck, or single-sheet woodcut, from the sixteenth century shows early incendiary devices used to honor the entry of the Holy Roman Emperor in 1530. The large woodcut displays the military honors given to the emperor: cannons firing on a castle constructed for the occasion and fireworks. Harnessing the potential of powders for both pyrotechnics and color added by hand to prints was among the many cultural developments of the sixteenth century. This article makes known a recently rediscovered impression of the print, unique with hand coloring, which serves as the focus of discussion for several aspects of the print including the ephemeral and incendiary, the states, and
Science In Context: Special Issue: Lay Participation in the History of Scientific Observation, ed. Jeremy Vetter
Early modern Europeans routinely compared nature to a theater or spectacle, so it makes sense to examine the practices of observing real spectacles and performances in order to better comprehend acts of witnessing nature. Using examples from the history of fireworks, this essay explores acts of observing natural and artificial spectacles between the sixteenth and late eighteenth centuries and suggests these acts of observation were mutually constitutive and entailed ongoing and diverse exchanges. The essay follows the changing ways in which audiences were imagined or expected to react to fireworks and shows how these also shaped experiences of natural phenomena. Both natural and artificial spectacles were intended to teach morals about the state and nature, yet audiences rarely seemed to take away what they were expected to learn. The essay examines how performers thus sought to discipline audience observation, before exploring, in conclusion, how spectacle provided a vocabulary for discerning and articulating new natural phenomena, and sites for the pursuit of novel experiments.

Theatrical Heritage: Challenges and Opportunities, ed. Bruno Forment and Christel Stalpaert, Leuven University Press, 2015
William Bennett, an Englishman visiting Paris in 1785, was astonished by the final scene of Salieri’s Les Danaïdes, in which the underworld is “buried in such a shower of fire, that I wonder the Playhouse was not burned to the ground.” This article discusses how that effect was achieved, as part of a survey of technologies used in the eighteenth century to produce the effects of fire, lightning, and explosions on the operatic stage. Deriving insights from published treatises (such as Claude Ruggieri’s Elémens de pyrotechnie, 1802), payment records (such as those recording the use of lycopodium powder in a revival of Rameau’s Castor et Pollux in 1778), and eyewitness accounts (such as the description by Hivart, a cellist at the Opéra, of the rain of fire at the end of Les Danaïdes), I trace the development of theatrical pyrotechnics during the eighteenth century, their use within specific operatic genres, and their geographical distribution.

Abstract The availability of fire in high altitude alpine contexts was certainly significant for the late prehistoric pastoral frequentation. The Iceman’s discovery gives a good example: Ötzi had, in his belted pouch, a piece of Fomes fomentarius (a dried mushroom, containing pyrite powder, used as tinder) and a flint tool useful to strike a light. But no pyrite mass was found, maybe it had crumbled during use, and that’s likely why Otzi carried a couple of birch-bark containers with embers enveloped in fresh maple leaves. During the IV millennium BC, the above cited strike-a-light technology, was much more widely adopted: the recent finding of a flint tool, with specific wear traces, on the Monte Baldo ridge (at 1734 meters a.s.l.) confirms that this kind of igniting kit was used in alpine areas, maybe in shepherding and/or hunting strategies. Even though igniting fire was a central function in prehistoric societies, fire representations seem mostly uncommon in rock engravings. But nevertheless, several ethno-archaeological sources highlight the importance, in the Alps area, of fire ignition as a sacral meaning, symbolized by lightnings and thunders, which also caused a reverential fear in people. For example: - ritual blazes (german: Brandopferplätze) on uplands as a message directed to divinities; - fires from the sky, ignited by lightnings, were considered as an expression of “thunder divinity”, such as “Giove Feretrio” (1) for the Romans, Perùn for the Slavs or Teshub for the Hittites. These considerations aim to promote a wider interpretation of rock engravings that could represent fire and/or lightning symbols, may be like “The Sorcerer” or “The tribal chief” of Monte Bego.

Early modern firework illuminations and displays formed part of festivities in both secular and sacred contexts from the end of the 14th century. During the 15th and 16th centuries their designers, often high-ranking artillery officers, became an increasingly important part not only of army but also of court life. The development of fireworks, and especially rockets, gave prominence to intricately conceived displays, which were gradually developed according to the changing tastes of musical theatre productions and the skills of masters of pyrotechnics. In Central Europe, several performances were staged at the Habsburg court from the middle of the 17th century onwards which were clearly among the most costly, complex and, above all, the highest-quality pyrotechnical displays of their kind in the history of human culture. They were instruments of the complex patterns of contemporary propaganda and courtly representation, and their stories reflected the reality, desires, visions and concerns of the ruling dynasty. We can deduce their forms, stories and messages from surviving synopses and printed illustrated sheets.

Sound waves are persistent in everyday life, although they are never seen. The particles of the average vibrations are parallel to the direction of propagation of the wave. In this article, the effect of changing the frequency of the sound wave on standing waves was investigated with different hertz frequencies to show technical images that can be visually translated to give fundamental predictions about the origin of the musical combinations, as it was proved that the sound is a pressure wave by giving the vibrations one side. At the same time, the gas is released on the other side. The variables were fixed in the experiment as the type of gas supplied for the same experiments to obtain accurate results. It is also installed so that the distance between the diaphragm and the amplifier does not differ. The results analyzed after numerous data collection and calculations verify that the generated wavelength and frequency are directly proportional. As the frequency specified in Hz inc...
