SummaryThe Monkton brooch was found in 1971 when mechanical trench digging disturbed a large Anglo-Saxon cemetery north of Monkton village on Thanet, east Kent. It is a large composite disc brooch made of electrum, silver, and gilded bronze, set with garnets, blue glass, and shell Consideration of its design, construction, and very pale, silver-debased, gold suggests that it was made no earlier than c. A.D. 640–50 and is amongst the latest of Kentish composite brooches.

The article features the gem of rather rare forms, namely so-called prisms, polyhedra, scaraboids and bifacial gems which were found in the burials of the Asian Sarmatia nomads. The author describes an attempt to attribute seals in the form of polyhedra from Sarmatian burials dated back to the 1st – first half of the 2nd century AD within the Lower and Upper Don and the Lower Volga regions. Polyhedra belong to the forms of gems, which became widespread in the Classical era, both among Greek and so-called Greek-Persian gems. In the 2nd – 1st centuries BC the seals in the form of polyhedra were widely distributed across the Caucasus and, especially, in Transcaucasia region. According to the finds, they are represented by numerous items made of carved stone, as well as of dark blue glass, milky white and greenish color. Moreover, there are also known rectangular forms of prints of such seals on the bulls, in particular which were excavated from the palace at Dedoplis Gora in Caucasian Iberia, dated to the 1st century BC – 1st century AD. The analysis of the shapes, materials and subjects of the images on the seals from the Sarmatian burials considered in the current article suggests that they were made in Transcaucasian workshops of the 2nd – 1st centuries BC. The probable Transcaucasian origin of the seals and their dating to the late Hellenistic period are an indirect confirmation of the hypothesis previously expressed by the author about the early cylindrical, conical seals and scaraboids of the mid-2nd – mid-1st millennium BC found in Sarmatian burials of the 1st century BC – 2nd century AD, originating from the sanctuaries of Transcaucasia.

Abstract The introduction of the folding stool and the single-edged razor into Southern Scandinavia, as well as the testimony of chariot use during the Nordic Bronze Age Period II (1500-1300 BC), give evidence of the transfer of ideas from the Mediterranean to the North. Recent analyses of the chemical composition of blue glass beads from well-dated Danish Bronze Age burials have revealed evidence for the opening of long distance exchange routes around 1400 BC between Egypt, Mesopotamia and South Scandinavia. When including comparative material from glass workshops in Egypt and finds of glass from Mesopotamia, it becomes clear that glass from those distant lands reached Scandinavia. The routes of exchange can be traced through Europe based on finds of amber from the North and glass from the South.

Reflected Light

Simultaneous measurements with two types of incubators were made on replicate samples both in the incubators and in situ in the ocean. Both incubators used sunlight and blue glass filters to simulate light conditions at depths in the ocean. The first gave measurements of column production 1.58 times those in situ. This was due to the fact that at depths greater than 20 m the incubator gave much higher results with no significant relation to those measured in situ. In the second incubator the accuracy of reproduction of oceanic light conditions was improved by reducing reflected light and using a balance-by-depth twin photometer system for determining the depths of sampling. The measurements of column production in the second incubator were 1.03 times the in situ values.

Abstract The Gilford Absorbance Indicator was recalibrated, for absolute absorbance readings, with (1) a U. S. Bureau of Standards calibrated cobalt-blue glass standard; (2) a standard cobalt ammonium sulfate solution at 512 mµ (3) standard potassium chromate solutions at 373 mµ These three standards agreed with 1%. Readings on the indicator's absorbance scale had decreased by about 7% over 2 years.

Ost of the gold ornaments represent the very splendid outer harness of a princely apparel, doubtless the sword-belt and baldrick, and also a purse and the straps on which it was slung. From the point of view of sheer weight of gold, the chief find was a huge and heavy buckle, inlaid with niello ; but the harness included twentyeight other pieces, all richly jewelled with garnets and, in some instances, blue and white mosaic glass. We must remember too that the sword has a jewelled gold hilt and two hemi-spherical bosses of gold, jewelled with garnet and blue glass, on the sheath (PLATE IX). There are also a number of minor fragments of gold, including one or two unornamented strap-mounts, two jewelled filigree strips of great delicacy, and a tiny mount of gold foil in the form of an animal. The excavators also found various ornamental fittings of wood or a similar material that were plated with gold.
