Abandonment of Minoan palaces on Crete in relation to the earthquake induced changes in groundwater supply

Mysterious abandonment of palaces on Crete during the Late Minoan period was always a challenging problem for archeologists and geologists. Various hypotheses explained this event by effects of tsunamis, earthquakes or climatic changes that were caused by the volcanic eruption of the Santorini volcano. While each of them or their possible combination contributed to the abandonment of palaces and following Late Minoan crisis, there is another possible cause that appeared as a result of studies within the last 20–30 years. This cause is depletion of groundwater supply caused by persistent earthquake activity that took place during the Bronze Age. This explanation is supported by field observations and numerous studies of similar phenomena in other locations.     

Olive oil production on bronze age Crete: nutritional properties, processing methods and storage life of Minoan olive oil

Archaeological studies on olive oil produced in Crete in the Bronze Age focus primarily on aspects such as the period when olive cultivation became widespread, the number of olive trees cultivated, or the quantity of oil stored in the Minoan palaces. Olive oil is however an organic substance, a perishable product, the nutritional and storage properties of which are determined by environmental, agronomic, processing and storage conditions. In this paper archaeological, environmental and biochemical evidence is combined to present a comprehensive picture of the potential quality, nutritional and storage properties of Minoan olive oil. The comparative evidence presented suggests that Minoan olive oil was equal in quality to the cold-pressed virgin olive oils produced today, and as such, the oil was nutritionally important in the Bronze Age and a valuable trade commodity.     

THE SEALING STRUCTURES OF MINOAN CRETE: MM II PHAISTOS TO THE DESTRUCTION OF THE PALACE OF KNOSSOS

Summary. The thousands of MM clay sealings in Room 25 of the First Palace of Phaistos testify to the importation into Crete of the Near Eastern system of storeroom administrative controls. Minoan practice then diverged from the Near Eastern model. The development of a recognizably Minoan sealing system is illustrated by the LM IB sealing deposits from Ayia Triada, Zakro and Khania (with something of its evolution traceable via Mallia and Knossos). Despite many common practices in LM IB, however, important local differences coexisted within this Minoan system, perhaps suggesting the absence of a single overriding administrative authority at this time.     

THE SEALING STRUCTURES OF MINOAN CRETE: MM II PHAISTOS TO THE DESTRUCTION OF THE PALACE OF KNOSSOS.

Summary. Middle Minoan Knossos shares in the sealing evolution which we have seen elsewhere on the island (SSMC I): the earliest sealings are placed directly on objects, a practice which, in time, generally yields to nodules which hang on cords (first crescents, then prismatic types) and flat-based nodules which were pressed over leather strips, presumably parchment documents. We have no LM IB sealings from Knossos, a site which might have been expected to have evolved its own local version of the Minoan sealing system. Sealings from the final destruction deposits at Knossos are at once closer to the earlier practices from Phaistos and to the later system known from the mainland. The mainland connection is seen in a reduction of sealing shapes (especially the disappearance of flat-based nodule types) and in a non-intensive, non-elite pattern of seal use.     

THE LIFE OF BUILDINGS: MINOAN BUILDING DEPOSITS IN AN ECOLOGICAL PERSPECTIVE

Summary. This paper discusses the interpretation of the objects deliberately hidden and sealed up in the structure of Minoan buildings. These building deposits are usually interpreted in terms of religion and ritual but this conventional view may actually be based on fallacious assumptions about the nature of human-environment relations in Bronze Age Crete. The present paper outlines an alternative ecological approach, which allows a degree of sociality between humans and non-human entities, and treats building deposits as an essentially practical means of manipulating the relations between humans and the (built) environment in situations of potential stress. It will be argued that buildings and other artefacts can, in some respects, be understood to live and grow similarly as organisms. Thus, in order to appreciate their significance, Minoan building deposits need to be related to the life-cycle of buildings.     

Colour in Minoan faience

The microstructures and chemical compositions of some 15 faience objects from Crete spanning the period from Middle Minoan IIIA through to Late Minoan IA are determined using analytical scanning electron microscopy. The Minoan faience is compared with replicate faience beads produced in the laboratory using various combinations of manganese, copper and iron as colorants. The alkali contents of the replicate beads are varied so that the colorants are present both as ions in a glass phase and as particulate oxides. These data are then used to try to infer the original colour of the Minoan faience, the great majority of which has suffered severe weathering during burial. The results suggest that instead of the present day “hallmark greys and browns” and “subtle greens and blues”, Minoan faience originally exhibited a wide range of colours, including bright turquoise blue, purple and violet, and pale yellow-green and greenish turquoise.     

Assessing the role of architecture in conspicuous consumption in the middle minoan I–II periods

Summary.  This paper uses Middle Minoan architecture to explore the degree to which the conceptualization and reconstruction of the First Palaces on Crete have been unduly influenced by the model of the Minoan palace as the centralized political, economic and religious authority. It is generally assumed that this model, first formulated on the basis of the LM II–III palace at Knossos, also serves to explain the First Palaces despite the fact that relatively little attention has hitherto been paid to their external and internal characteristics. Detailed reassessment of the available data strongly suggests that the First Palaces differed from their Late Bronze Age counterparts in several important ways. Particularly striking is the absence of so-called 'palatial' architectural features (e.g. ashlar masonry, Minoan Hall, Lustral Basin, etc.), which hitherto had been thought to form an integral part of the First Palaces. Rather, the earliest evidence for these architectural features seems to be found in elite residences in settlement contexts (e.g. Malia). This observation urges a reassessment not only of the term 'palatial' architecture but also of the nature and location of power in Middle Bronze Age Crete and the role played by architecture as a medium of elite conspicuous consumption.     

THE WESTERN CYCLADES and CRETE: A "SPECIAL RELATIONSHIP"

Summary: This paper examines the idea that in the Later Bronze Age a regular exchange network linked Crete to the Western Cyclades and assured them of preferential treatment. Comparison of the degree of Minoan influence on Keos, Melos and Thera with that on the other Cycladic islands confirms that the former group had a special relationship with Crete; but the evidence is insufficient to prove that they acted as secondary distribution centres for Minoan goods. the substantivist view is that in a non-monetary economy exchange was effected through reciprocity and redistribution, while early trade was always motivated by imports, not exports. But documentary evidence for the Near East warns against oversimplification. For the Western Aegean, precise data are lacking, but evidence suggests that foreign trade was regulated by official agents; there was also freelance private enterprise. the Western Cyclades derived much of their prosperity from the transit dues.     

On the flow characteristics of the conical Minoan pipes used in water supply systems,via computational fluid dynamics simulations

The Minoan Terracotta pipes with their conical shape were widely used in the water distribution system in the ancient Minoan civilization. They remain one of the brightest achievements of the Minoan tribe in water supply technology and raise admiration as well as many questions about the technological advancements of antiquity, that are yet to be understood. The present work aims at answering the following questions: a) what inspired the Minoans to manufacture pipes with such a peculiar shape, that differs greatly not only from later pipe designs of antiquity, but also from contemporary cylindrical pipes and b) why was the design of those pipes abandoned after the fall of the Minoan civilization? It tries to address these questions by investigating the flow physics and dynamics that take place in such pipes, adopting advanced numerical and computational methods. The time-averaged Navier–Stokes equations along with the k − ? turbulence model are solved for a variety of geometrical parameters, pipe orientations and flow rates, in order to produce a comparative picture of the hydraulic efficiency of the conical Minoan pipes. The flow field is visualized and critical flow parameters, such as the head loss, the velocity magnitude and turbulence intensity, are calculated. These calculations show clearly that the conical Minoan pipes exhibit significantly higher pressure drops along their length compared to an equivalent straight pipe. In their widest part an extended recirculation appears, which could wash out impurities that may be present in the water, which at the same time cannot be deposited on the pipe wall. This evidence proves that the Minoan pipes are energetically expensive to operate and consequently their replacing by cylindrical pipes was inevitable. Therefore, it seems that the main advantage and purpose of the particular geometry was that they could be easily connected on site, forming long straight or slowly bending lines without having to add straight or many different fittings in between.     

THE MULTIPLE SEALING SYSTEM of MINOAN CRETE and ITS POSSIBLE ANTECEDENTS IN ANATOLIA

Summary: The Multiple Sealing System ( MSS ) is defined as the habitual stamping of regular combinations of two or three different seal impressions on clay nodules ( bullae ). This system was thought to be peculiar to LM IB Zakro, where it is indeed most fully developed, but a Minoan MSS can now be traced back - via MM IIIB Knossos - to the earliest administrative use of sealings on Crete, at MM IIB Phaistos. This early MSS at Phaistos has close links with a similar administrative use of seals in regular combinations at Karahöyük Level I. We suggest that the MSS is a new and objective factor to be added to the known, if often disputed, glyptic relations between MBA Anatolia and Minoan Crete.     

ABSOLUTE DATING OF THE AEGEAN LATE BRONZE AGE

A recent argument for raising the absolute date of the beginning of the Aegean Late Bronze (LB) Age to about 1700 B.C. is critically examined. It is argued here that: (1) the alabaster lid from Knossos did have the strati-graphical context assigned to it by Evans, in all probability Middle Minoan IIIA, c. 1650 B.C.; (2) the attempt to date the alabastron found in an early Eighteenth Dynasty context at Aniba to Late Minoan IIIA:1 is open to objections; (3) radiocarbon dates from Aegean LB I contexts are too wide in their calibrated ranges and too inconsistent both within and between site sets to offer any reliable grounds at present for raising Aegean LB I absolute chronology to 1700 B.C. Other evidence, however, suggests this period began about 1600 B.C., i.e. some fifty years earlier than the conventional date of 1550 B.C.     

The Achaian Vapheio Cup and Its Afterlife in Archaic South Italy

Summary.   This article publishes an Archaic Greek cup of individual form from the extramural sanctuary of the Achaian colony of Sybaris at Francavilla Marittima in south Italy. The Francavilla cup, which is Achaian or Achaian-style, is fully discussed and similar Archaic cups from the site of Incoronata, near the Achaian apoikia of Metapontion, are assembled. These vessels find no immediate parallel among contemporary Greek or indigenous pottery of the seventh and earlier sixth centuries BC, but bear a remarkable similarity to the characteristic cylindrical, so-called Vapheio cups of the Aegean Bronze Age which are known in metal, clay and stone versions from as early as the Early Minoan III period through the Late Helladic era. It is argued that these cups represent the Archaic creation or re-creation of a well-known Bronze Age shape in the Achaian apoikiai of south Italy.     

Geoarchaeological tsunami deposits at Palaikastro (Crete) and the Late Minoan IA eruption of Santorini

The explosive eruption at Santorini in the Aegean Sea during the second millennium BCE was the largest Holocene volcanic upheaval in the Eastern Mediterranean region. The eruption was disastrous for the Minoan settlements at Santorini, but the effect on human society in the neighbouring islands and regions is still clouded in uncertainty. Tsunami generation was suggested, but comparatively little evidence was found. The lack of firm tsunami traces is particularly puzzling in Crete with its coastal settlements of the Late Minoan IA period, during which the Santorini eruption occurred. Here, we report the discovery of extensive geoarchaeological tsunami deposits at Palaikastro in north-eastern Crete. These deposits are characterized by a mixture of geological materials, including volcanic Santorini ash, and archaeological settlement debris. Various tsunami signatures were identified: (1) erosional contact with the underlying strata, (2) volcanic ash intraclasts in the lower part of the deposit, (3) reworked building stone material in the lower part of the deposit, (4) individual marine shells, (5) marine micro-fauna, (6) imbrication of rounded beach pebbles, settlement debris, ceramic sherds and even bones, (7) multi-modal chaotic composition. Late Minoan human settlement activities at Palaikastro provided architectural and stratigraphic frameworks in space and time that recorded and preserved tsunami evidence as geoarchaeological deposits. Such stratigraphic resolution and preservation may not occur in the natural landscape. Volcanic ash transported by wind from Santorini south-east to Crete preceded the tsunami. Geological, archaeological and radiocarbon dating criteria all converge, indicating that the tsunami deposits are coeval with the Minoan Santorini eruption. Field evidence suggests that tsunami waves at Palaikastro were at least 9 m high. Inverse tsunami modeling was attempted, based on these newly discovered tsunamigenic deposits. The initial wave in the generation region at Santorini that best fits the stratigraphic data is a wave with +35 to −15 m initial amplitude and a crest length of about 15 km.     

Contouring the Cataclysm: A Geographical Analysis of the Effects of the Minoan Eruption of the Santorini Volcano

This study is a step forward in understanding the palaeoenvironmental effects of the Minoan eruption of Santorini (1627–1600 BCE). We employ geostatistics to produce a prediction map for the thickness of the tephra fallout over the Eastern Mediterranean, and we reconstruct the effects by comparisons with recent eruption analogues. Based on the geostatistical map, the amount of environmental disruption over so far undocumented areas is estimated by comparison with archaeological sites where emplaced Minoan tephra has been recorded before. Nevertheless, independent field evidence suggest that the environment responded differently in places, occasionally posing challenges to the presented interpolation. A second line of evidence coming from contemporaneous fluvial archives provides clues for a widespread ‘Minoan flood’ over a large part of the Eastern Mediterranean, associated with the eruption itself. This simultaneous hydrological event may have had a counterbalancing effect on the impacts of the Minoan tephra cover, and could explain the sporadic discrepancies between the predicted effects and the palaeoenvironmental evidence. Traces of the effects of this extraordinary volcanic event are also sought in the regional Late Bronze Age literature.     

COMMENTS ON A POPULAR MODEL OF MINOAN RELIGION

Summary. The theory that worship of a great goddess dominated Minoan religion to such an extent that it can be described in almost monotheistic terms remains commonplace in accounts of Minoan civilization. The intellectual bases of this theory are questioned, and alternative approaches are suggested.     

A Bronze Age Quarry in Eastern Crete

Abstract

The sandstone quarry at Mochlos is one of four major quarries in eastern Crete that were worked during the New Palace Period of Minoan civilization (ca. 1700–1450 B.C.) to produce large ashlar blocks for nearby Minoan sites. At that time sandstone, or ammoudha, as it is known locally, was especially valued as a building material, partly because of its distinctive color and texture, but mainly because of the ease with which it could be cut, and the stone was used extensively for exterior façades, for walls around interior courts, and for other architectural features of the more important buildings on these sites. This article describes the quarry at Mochlos in some detail, including the quarrying techniques employed, and argues that the destination of the stone from the Mochlos quarry was the Minoan palace at Gournia. The article ends with a comparison of the four ammoudha quarries in eastern Crete.     

Representations of birds in Minoan art

During the second millennium BC , the Minoan civilization was established in the southern Aegean Sea. In Minoan art, especially on Crete, birds occupied a prominent place, and were often represented in wall-paintings and craft objects. Species still occurring on the island, such as cormorants, mallards, cuckoos, owls, hoopoes, and swallows, as well as exotic taxa such as partridges and possible domestic forms such as pigeons, were the subject of artistic inspiration, and they were depicted not only in purely cult contexts, but also in the backgrounds of naturalistic landscapes. The aim of this paper is to reconsider the identification of some of the birds depicted and to discuss them in the context of the environmental conditions and osteological finds from the southern Aegean islands in Minoan times. © 1997 John Wiley & Sons, Ltd.     

Developing a documentation system for desert palaces in Jordan using 3D laser scanning and digital photogrammetry

Desert palaces in Jordan are unique pieces of art scattered in the desert as standing symbols of ancient civilizations. Due to their location, these palaces witness different environmental conditions which affect their status and sustainability. This raises the need to have a 3D documentation system reporting all spatial information for each palace, which can be used later for monitoring purposes. Digital photogrammetry is a generally accepted technique for the collection of 3D representations of the environment. For this reason, this image-based technique has been extensively used to produce high quality 3D models of heritage sites and historical buildings for documentation and presentation purposes. Additionally, terrestrial laser scanners are used, which directly measure 3D surface coordinates based on the run-time of reflected light pulses. These systems feature high data acquisition rates, good accuracy and high spatial data density. Despite the potential of each single approach, in our opinion, maximum benefit is to be expected by a combination of data from both digital cameras and terrestrial laser scanners. By these means the efficiency of data collection as well as the geometric accuracy and visual quality of the collected textured 3D models can be optimized. Within the paper, a 3D documentation system for Umayyad desert palaces in the Jordan desert will be presented using digital photogrammetry and laser scanning. The approach is demonstrated by generating high realistic 3D textured models for Amra and Kharanah palaces.     

TEPHRA SAMPLES FROM MOCHLOS AND THEIR CHRONOLOGICAL IMPLICATION FOR NEOPALATIAL CRETE

Five deposits of Santorini tephra have been found in the excavations currently under way at the site of Mochlos which lies on the north coast of Crete about 140 km to the south of Santorini. This paper provides refractive index and trace element analyses for the largest of these deposits, examines the stratigraphy of all five deposits, and notes the chronological implication of this stratigraphy for the Late Minoan IB period, the floruit of Minoan civilization.
