A Portuguese East Indiaman from the 1502–1503 Fleet of Vasco da Gama off Al Hallaniyah Island,Oman: an interim report

Two Portuguese naus from Vasco da Gama's second voyage to India, left behind to disrupt maritime trade between India and the Red Sea, were wrecked in May 1503 off the north‐eastern coast of Al Hallaniyah Island, Oman. The ships, Esmeralda and São Pedro, had been commanded by da Gama's maternal uncles, Vicente and Brás Sodré, respectively. A detailed study and scientific analysis of an artefact assemblage recovered during archaeological excavations conducted in Al Hallaniyah in 2013 and 2014 confirms the location of an early 16th‐century Portuguese wreck‐site, initially discovered in 1998. Esmeralda is proposed as the probable source of the remaining, un‐salved wreckage.     

An Early Portuguese Mariner's Astrolabe from the Sodré Wreck‐site,Al Hallaniyah,Oman

A unique leaded‐gunmetal disc decorated with iconic Portuguese markings was recovered in 2014 during archaeological excavations at the Sodré shipwreck site in Al Hallaniyah, Oman. Initially the identity and function of the disc was unknown, although it did possess characteristics suggesting it could be an astrolabe. Laser imaging of the disc post conservation revealed regular scale marks on the limb of its upper right quadrant. Accurate digital measurements of the marks show them to be graded at close to 5‐degree intervals, thus confirming the identity of the disc as a mariner's astrolabe and the earliest known example discovered to date.     

Portuguese Blue‐on‐Blue 16th–17th Century Pottery

Blue‐on‐blue (‘berettino’) sherds have appeared in numerous production and consumption archaeological excavations in Lisbon and other archaeological sites in Portugal (dated from the mid‐16th century to the beginning of the 17th century). The abundance of this interesting faience led us to compare it with similar pottery from other well‐known production centres in Italy, namely Liguria (Savona and Albisola), Spain (the Triana kilns) and the Low Countries. Differences in the diffraction patterns of the sherds' pastes from the four countries were observed. In most samples, cobalt blue silicate (cobalt olivine) was identified in the dark blue or light blue glazes through the use of micro‐Raman spectroscopy and diffuse reflectance spectra. A remarkable difference in the calcite contents of the Lisbon and Seville pottery sherds was observed, in accordance with previous observations of high calcite contents of Seville ceramics. A comparison was also made for all of the blue‐on‐blue sherds studied here with many other 16th–17th century sherds from Lisbon using bivariate plots of K/Si versus Ca/Si. Lisbon and Seville pottery behave very differently, whereas sherds from Italy and the Low Countries occupy intermediate positions.     

The 19th‐Century Akko 1 Shipwreck,Israel: hull‐construction report

The Akko 1 shipwreck was found in 4 m of water inside the ancient harbour of Akko, Israel, and was fully recorded under water. Several hull‐components were retrieved and documented on land, as well as all the finds. The results of the archaeological research and the study of the historical background suggest that the Akko 1 shipwreck is the remains of an eastern Mediterranean naval auxiliary brig, built at the end of the first quarter of the 19th century, and sailing under the Egyptian flag. The ship was apparently wrecked during the 1840 naval bombardment of Akko. © 2012 The Authors     

A 15th‐Century Wreck of an Ordnance‐Carrying Ship from Atlit North Bay,Israel

In 1977, a shipwreck assemblage was discovered off Atlit, Israel. Finds included three iron anchors, a large bombard, four swivel guns, stone and lead shot, and bronze helmets. The bronze bombard (2210 kg, 3.247 m long) contained a wooden wad and remnants of what may have been gunpowder. The swivel guns (each 185 kg) were bronze, with swivels and the tillers of iron. Twenty (or 21) bronze helmets were recovered. The findings provide rare evidence for the mounting of heavy ordnance on the bow of a galley or ship in the 15th century.     

Occipitalization of the Atlas in Archaeological Material from the 16th–19th Century

During the anthropological analysis of skeletal material dated in the 16th–19th century from St Katarina monastery in Split, a female skull with occipitalization of atlas has been found. Anterior part of atlas and foramen magnum were fused, with numerous perforations on auricular surface of atlas. As the age at death was estimated at more than 70 years, it is most likely that this woman had progressive course of illness. Copyright © 2012 John Wiley & Sons, Ltd.     

A Late 17th‐Century Trade Cargo from Ponta do Leme Velho,Sal Island,Cape Verde

In 1973, while recovering copper cargo from a 20th‐century ship wrecked off the Ponta do Leme Velho on the south‐east side of Sal Island, Cape Verde, explosives revealed an earlier ship cargo with dozens of Portuguese faience plates and bowls, glass beads and metal objects, including buckles, ammunition and copper manillas. The assemblage, including the ceramics and a marked silver tastevin, provide a site date between 1680 and 1700. The research presented here is a result of collaboration between CPAS and the authors in 2008 to analyse this assemblage in the context of late 17th‐century maritime trade.     

Archaeology of the Early 19th‐Century American Steamboat Phoenix

In September 1819, the passenger steamboat Phoenix caught fire on Lake Champlain and sank off of Colchester Shoal, Vermont, depositing a store of archaeological data on the design and use of early American steamers. The wreck is believed to be the earliest example of a steamboat that has yet been investigated archaeologically, and has been used as a case study for the early development of steam propulsion in North America.     

A 16th‐Century Ship‐Find from Amager Beach Park,Denmark: description and preliminary interpretation

When establishing the new Amager Beach Park near Copenhagen, Denmark, a small clinker‐built ship dating to the 16th century (dendro‐dated to 1560–70) was discovered. The Viking Ship Museum in Roskilde excavated the wreck in 2004, and parts of the ship were later taken to the museum and recorded in 3D. This article describes the excavation and the documentation, and presents the preliminary interpretation of the ship‐find. The ship is interpreted as a small cargo vessel, probably carrying two masts. Its hull‐form indicates that the vessel was specially designed for navigating the waters of the Sound between Denmark and Sweden. © 2010 The Author     

Problems of Analysis by FTIR of Calcium Sulphate–Based Preparatory Layers: The Case of a Group of 16th‐Century Portuguese Paintings

This paper provides a contribution to FTIR analysis of calcium sulphate‐based grounds of paintings when a mixture of compounds with different degrees of hydration is present. The study is based on the analysis with that technique, electron microscopy coupled with energy‐dispersive X‐ray spectrometry and X‐ray diffraction of both the grounds of 16th‐century Portuguese paintings and reference samples prepared with anhydrite and calcium sulphate dihydrate bound in an animal glue solution. It is shown that the interpretation of the degree of hydration of calcium sulphate ground samples using FTIR cannot be based solely on the study of the hydroxyl bands, as is usual in routine work, but that small deviations of the S–O vibration bands are an important indicator of the presence of anhydrite in the grounds.     

‘Novy Svet Ware’, an Exceptional Cargo of Glazed Wares from a 13th‐Century Shipwreck near Sudak (Crimea,Ukraine)—Morphological Typology and Laboratory Investigations

Excavation of a medieval shipwreck at Novy Svet, Crimea, Ukraine, revealed an exceptional quantity of glazed ceramics with sgraffito decoration which, according to chemical analysis, correspond to a single production provisionally named ‘Novy Svet Ware’. Typological and analytical definitions are given. Its diffusion in the Crimea and extending to Turkey and the Levant, points to a main, as yet unlocated, workshop. The Novy Svet shipwreck suggests the persistence of large‐scale diffusion of ceramics in the late‐13th century, and demonstrates connections with the Black Sea, the Byzantine capital and territories, the Mediterranean and possibly the spice roads. © 2009 The Authors     

Global Markets, Local Practice: Ottoman-period Clay Pipes and Smoking Paraphernalia from the Red Sea Shipwreck at Sadana Island, Egypt

Shipwreck archaeology provides unique evidence for trade, commercial relationships, and the day-to-day existence of occupational communities defined by residence and employment within the industrial space aboard a ship. These concerns are addressed particularly well by finds of utilitarian items such as a small assemblage of 21 clay pipes and three other smoking-related artifacts recently excavated from the ca. 1765 Sadana Island ship which sank at anchor while loaded with coffee, porcelain, qulal, and other goods. Analysis of the assemblage specifically contributes to questions of chronology and typology and presents new evidence for regionalism, style, and the impact of far-reaching trade routes on markets with a global perspective.     

An Osteobiography of a 19th‐Century Dog from Toronto,Canada

A 19^th‐century dog burial uncovered from a historical homelot in Toronto, Canada, provided a unique opportunity to reconstruct the individual's osteobiography. Of particular interest are the dog's very large size and a suite of skeletal pathologies. Recovery of a nearly complete skeleton combined with the use of X‐rays and micro‐computed tomography (micro‐CT) allowed for a discriminating differential diagnoses. Stable isotope analyses were applied to investigate questions of diet. Results reveal an individual who suffered greatly from disease towards the end of his life and hint at its owners attitudes towards dogs. The interdisciplinary approach applied to this case study highlights the potential information obtainable from pet burials. We argue that better analyses and reporting of pet burials will help address research questions targeting broader themes related to human–animal relationships.

The Hull of Yenikapı Shipwreck YK 11: a 7th‐century merchant vessel from Constantinople's Theodosian Harbour

YK 11, a small, heavily repaired merchantman, was one of 37 Byzantine shipwrecks excavated at Yenikap? in Istanbul, Turkey. This 7th‐century hull, abandoned in the harbour as a derelict, was studied by archaeologists from the Institute of Nautical Archaeology. Originally built with mortise‐and‐tenon edge joinery, the ship had undergone a series of significant repairs over its lifetime. Repairs included the replacement of planking as well as framing. Although the repaired vessel exhibits evidence of both shell‐first and skeleton‐first shipbuilding techniques, detailed study of the hull remains indicates that the ship was initially designed and built as a primarily shell‐based vessel.     

Electron Microprobe Analysis of 9th–12th Century Islamic Glass from Córdoba,Spain

Twenty‐six samples from domestic assemblages of 9th–12th century Córdoba were subjected to electron microprobe analysis. The results reveal two main compositional types. The first, encountered in 13 of the samples, seems to result from the combination of plant ashes with high‐impurity sand, and has some contemporary parallels from Syria and Egypt. The second type is a lead–soda–silica glass, encountered in a relatively high proportion of the glasses (11 of the 26 sampled), possibly formed by the addition of lead metal to existing glasses and with very few known parallels. These are among a very small number of results available to date on the chemical composition of glasses from medieval Spain, and the presence of a high proportion of lead–soda–silica glasses is particularly interesting, possibly indicating a technological practice unique to, or originating in, the western Muslim world.     

High‐boron and High‐alumina Middle Byzantine (10th–12th Century ce) Glass Bracelets: A Western Anatolian Glass Industry

The trace element boron is present in most ancient glasses as an impurity, and high boron (≥ 300 ppm) marks raw material sources that are geologically specific and relatively uncommon. Recent analyses of Byzantine glass with high boron contents suggest that glass‐making was not limited to the traditional regions of the Levant and Egypt, and a production origin in or near western Anatolia is proposed. Glass bracelets from ?i?n al‐Tīnāt in southern Turkey give fresh evidence for the production and circulation of high‐boron glasses that closely correlates with object typology. The patterning of findspots suggests that high‐boron glass was closely connected to the Byzantine world.     

Glass Beads from 15th–17th Century CE Jar Burial Sites in Cambodia's Cardamom Mountains

A total of 74 glass beads, included as grave goods in 15th–17th century CE jar burials from Cambodia's Cardamom Mountains, were analysed using laser ablation – inductively coupled plasma – mass spectrometry (LA–ICP–MS). Several glass types were identified, including two subtypes of high‐alumina mineral soda glass, and lead–potash glass. The final glass type represents a newly discovered and previously unidentified type of high‐alumina soda glass, with high magnesia (m‐Na–Al Mg>). This study represents the first glass data from the mid‐second millennium CE from Cambodia and sheds light on the multiple long‐distance maritime exchange networks in which the upland people buried in the jars were participating.     

The Militia Ordinance of 1642 and the 14th‐Century Great Statute of Praemunire

This article opens with a review of the important scholarship concerning the conflict over prerogative between the crown and parliament from mid 1641 through the winter of 1642. The resulting impasse was over which of these institutions would control the militia. This article argues that the Militia Ordinance committee was committed to ‘the legal process’ in developing its directive of March 1642. The balance of the study reviews the medieval Statute of Praemunire, its subsequent development, and how that law would have provided an essential basis for the parliament to assume control of the militia. The article concludes that the Long Parliament acted legally with the Great Statute of Praemunire as a reference point for the adoption of the Militia Ordinance. This conclusion rests on five evidentiary considerations: (i) surviving texts of Commons’ private diarists; (ii) the probable role of John Selden in the Militia Ordinance committee deliberations; (iii) the September 1642 publication of John Marsh's An Argument Or, Debate In Law of the Great Question Concerning the Militias; (iv) proposition five of the Nineteen Propositions; and (v) language parallels between the 1393 Great Statute and the Militia Ordinance itself.     

A Late‐18th‐Century Merchantman Wrecked in the South Edinburgh Channel,Thames Estuary,England

The South Edinburgh Channel wreck consists of the remains of a large, unidentified armed merchant ship whose cargo included a rare consignment of Swedish plate‐money, among other goods. The wreck was lost some time in the later part of the 18th century in the Thames Estuary and was uncovered briefly by natural means between 1972 and 1977. This allowed archaeological investigation, which was undertaken in very poor environmental conditions in the early days of maritime archaeology in the UK.
