La Mer D'eau Douce
ROBERTO J. PAYRO LA MER D’EAU DOUCE XII ENTRE MER ET CIEL La journée était très belle, le vent favorable, la mer un immense manteau vert foncé ondulé par de légères et longues vagues. La proue orientée vers les Canaries, vers le sud-ouest, naviguant au large, le vent presque en poupe, on devait peu manoeuvrer sur les caravelles et l’équipage se reposait en profitant de la vie. Solís était descendu dans sa cabine, confiant le pont à son second, le pilote Juan de Lisboa (N.d.T. : Alvarez de Cartaya ; voir chapitre 10) ; dorénavant on allait peu le voir, si ce n’était à l’entrée et la sortie du port éventuel, lorsqu’il désirait prendre personnellement la direction et dans un cas difficile. Mais, matins et soirs, on allait l’entendre quotidiennement héler les capitaines des autres caravelles, commandées, l’une par Francisco de Torres, secondé par le quartier-maître Diego García de Moguer, et l’autre par le pilote Rodrigo Alvarez. Porte-voix à la main et, après avoir écouté ces capitaines, Juan Díaz de Solís donnait ses ordres : en général, ils consistaient simplement à continuer de cingler en naviguant de conserve durant le jour et, la nuit, à suivre la lanterne de la caravelle portugaise, qui dirigeait la marche. Dieu leur avait procuré la sécurité – comme disaient les Musulmans –, et les jours suivants furent semblables à ce 13 octobre 1515, premier jour de voyage en haute mer, avec du vent frais et des éclaircies telles que rien ne perturba jamais la tranquillité de la navigation. -
The Use of CANNON in the CIVIL WAS with Particular Reference To
The Use Of CANNON IN THE CIVIL WAS With Particular Reference to DERBYSHIRE by R. HAYHURST Published by the Local History Section of the DERBYSHIRE ARCHAEOLOGICAL SOCIETY Because of the interest occasioned by ray previous article, (DerbyshireMiscellanyVol.il No.6 p.318-9) and through the useful suggestions of members, I am encouraged to submit these notes, which I hope-will assist in clarifying the picture so far as the use of guns in Derbyshire is concerned. It appears desirable, in order to place the matter in its proper context, to review the situation generally, and to this end I have consulted various works, including the following, to which I am indebted for numerous extracts; Whitelock's Memorials, 1682; Rushworth's Collections, 1659-1701} "Cromwell's Army", by C . H. Firth, 1902} "Castles and Cannon", B. H. St. John O'Neill, "Life of Col. Hutchinson", Lucy Hutchinson} "Memoirs of the Duke of Newcastle", by Margaret, Duchess of Newcastle} "Derbyshire", Pilkington; "Waterloo", John Naylor, I960; and "The Story of the Gun", by Lt. A. W. Wilson, R.A., 1944* Firth quotes expensively from earlier writers, as "Animadversions of War", 1639, "Principles of the Art Military", 1643, etc. Appended to a particular edition of "The Life of Col. Hutchinson" is an excellent day to day account of the Siege of Lathom House. From the gunnery standpoint St. John O'Neill is disappointing, as buildings were his interest and he refers to the gun only insofar as it affects castles and fortifications. Generally there are masses of references to the use of guns, but only very infrequently does one find precise information as to range and effect, and the picture must be built up by extracting appropriate evidence from numerous actions. -
A Late Medieval Or Early Modern Light Gun Barrel from the Castle Museum in Malbork—Typology, Technology of Manufacture and Identification of the Smelting Process
Archaeological and Anthropological Sciences (2019) 11:2007–2026 https://doi.org/10.1007/s12520-018-0653-3 ORIGINAL PAPER A late medieval or early modern light gun barrel from the Castle Museum in Malbork—typology, technology of manufacture and identification of the smelting process Grzegorz Żabiński1 & Mateusz Biborski2 & Ewelina A. Miśta-Jakubowska3 Received: 9 February 2018 /Accepted: 3 May 2018 /Published online: 18 May 2018 # The Author(s) 2018 Abstract The paper discusses a gun barrel of a possibly late 15th-early 16th c. date from the collection of the Castle Museum in Malbork (Marienburg), Poland (MZM/468/MT). The barrel was originally part of a hand-held gun (a hackbut?) and was later converted into a light cannon. The barrel was made from unevenly carburised soft steel (c. 0.1–0.2% C). Both metallographic examinations and the analysis of slag inclusions with the use of multivariate statistics suggest that the metal in the barrel was manufactured using the direct (bloomery) smelting process.

Prices of Weapons and Munitions in Early Sixteenth Century Holland During the Guelders War1
James P. Ward Prices of Weapons and Munitions in Early Sixteenth Century Holland during the Guelders War1 1. Introduction The adage that to have peace one has to prepare for war may not be of Classical antiquity but the principle was known to Livy and the Ancients,2 and so the influence of the weapons industry on world peace and economy hardly needs to be emphasized now. The purpose of this article is both to present data on retail prices of individual weapons and munitions of war in the first decades of the sixteenth century in Holland, and to show how the magistrates there prepared to defend their cities against an aggressor by purchasing weapons to arm the citizens. Prices quoted here for strategic commodities of war in the early sixteenth century complement those given by Posthumus in his survey of prices for the later sixteenth century and beyond.3 Kuypers published inventories of weapons maintained in castles and elsewhere in Holland and the Netherlands in the first half of the sixteenth century, but the cities of Holland were not included in his descriptions.4 A recent study by De Jong reveals the growth of the early modern weapons industry in the Republic of the United Netherlands in the period 1585-1621 as part of a process of state formation based on entrepreneurship, economic growth and military reform.5 As sources for the present investigation accounts of the Treasurer for North-Holland at The Hague, and of the city treasurers of Haarlem, Leiden, Dordrecht and Gouda were examined for expenditures on weapons and munitions. -

Financial Crisis, Euro Perspectives and the Balkans ______

We then look at the implications of the latter for the Balkans: do they imply trouble for the Balkan EU perspective? We also briefly sketch what needs to be done in institutional terms in order to prevent future crises. The main part of the paper is devoted to an assessment of the seminal proposal of a European Monetary Fund. We derive that it is a preferable blueprint in our context. We finally convey an outlook on different issues: first on the still open and critical issues in euro area crisis management, second on the interaction of bank and sovereign debt resolution and, finally, also on the future economic performance of the Balkans, i.e. Croatia, Macedonia joint with Turkey, with an 1 TP PT e-mail: [email protected] I am grateful for valuable comments from Fabrizio Coricelli, Camelia Turcu and other participants in the Conference 'Europe and the Balkans: economic integration, challenges and solutions', Orléans, February 3-4, 2011.

Bowl Round 2
2017-2018 IHBB Beta Bowl 2017-2018 Bowl Round 2 Bowl Round 2 - MS First Quarter (1) This country’s parliament recently held an underwater session to call attention to global warming, which threatens its population living on low-lying islands. This country’s population primarily speaks a language related to Sinhalese, spoken on Sri Lanka to its northeast. For ten points, name this Indian Ocean island nation that has become popular among honeymooning couples for its resorts featuring romantic bungalows that have been built over the water. ANSWER: Maldives (2) An early metal version of these objects was called the pot-de-fer, and culverins were portable types of these items. The Hungarian engineer Orban designed a massive one of these objects that malfunctioned and killed him. Vauban designed star forts to defend against these weapons, which Mehmed II used to destroy the walls of Constantinople in 1453. For ten points, name these gunpowder- based artillery pieces. ANSWER: cannons (or bombards; prompt on artillery before mentioned; prompt on supergun; do not prompt on gun, weapon, or other too-vague terms) (3) This country’s prominent businesswomen include Lubna Olayan, who gave a historic address in 2004 at the Jeddah Economic Forum. This country was the target of an incoming missile in 2017 that was fired by rebels in Yemen to its south. For ten points, name this country where, in 2017, King Salman lifted a restriction on driver’s licenses that will, eventually, allow women to drive in Riyadh and Mecca. ANSWER: Kingdom of Saudi Arabia (4) In 2010, nine activists trying to bring aid to this territory were killed when their “Freedom Flotilla” was raided.
