Pylos and Messenia Curt W. Beck and Lily Y. Beck S OON AFTER it was found that infrared spectroscopy offered a means of distinguishing the so-called Baltic amber of nor­ thern Europe from the many similar fossil resins found in virtually every European country, 1 the method was applied to the archaeological amber finds of Bronze Age Greece. The results were published in a series of four papers in this journal. The first of these2 reviewed earlier attempts to determine the provenience of Mycanaean amber finds by Helm and Jonas 3 and the reasons why these were methodologically inadequate. It then described the spectroscopic method of analysis, which has the advantage of requiring only a minute sample of no more than two milligrams, and the spectral features that allow the unambiguous recognition of the Baltic amber or succinite of northern Europe, i.e., a single absorption near 8.7 microns (1150 cm-1) preceded by a broad 'shoulder' that is perfectly flat in well­ preserved specimens but assumes an increasingly negative slope as weathering progresses. The introductory paper con­ cluded with the infrared analysis of five amber finds obtained from the late Professor Blegen during a visit to the Palace of Nestor in 1965.

The other four are from the Vayenas tholos (=tholos V), excavated by Lord William Taylour in 1957. Two of these (Chora Museum Inv. Nos. 2022a, 2046~) are not listed in the final report; 5 both arc of Baltic succinite. The other two (Chora Museum Inv. Nos. 2043~. 2055 a) 6 yielded infrared spectra that are just as certainly not those of Baltic succinite, but could not be correlated with any other European fossil resin at the time. We have since shown that these two spectra match those of Sicilian amber or simetite.l Subsequent reports have dealt with the amber finds from Tiryns, Kakovatos, and Mycenae. 8 We now complete the series with a report on the spectroscopic provenience analysis of amber finds from Pylos and related sites in western Messenia. Typology The most rational and comprehensive typology of bead shapes remains that of Horace Beck published 68 years ago. 9 Unfortunately, archaeologists have not widely adopted it, perhaps because, like any truly comprehensive typology, it is necessarily quite elaborate. It does, however, have the inesti­ mable virtue of basing its descriptive terms on the unam- ~ C. W. Blegen and M.

Thus a perforated sphere with a shortened axis, sometimes described as a flattened sphere, is properly and concisely called oblate, while a lengthening of the axis produces a prolate, sometimes described as an elongated sphere or an olive. The system has been usefully adapted to classify the Bronze Age amber beads of Hungary 10 and extended to classify the prehistoric amber beads of Britain from the Mesolithic to the Iron Age. 11 Two other published classifications of amber beads are of limited value because of their narrow scope. Tempelmann-Maczynska 12 deals only with the first five centuries of the present era. She distinguishes hand­ made from lathe-turned beads and lists 89 types in 26 groups, with a good deal of overlap. Her descriptive terms are allusive rather than geometric, e.g., "heart-shaped," "drum-shaped," "bucket- shaped," etc. An attempt to correlate the shapes of the Messenian amber beads with the typology of Xenaki-Sakel­ lariou 13 had to be abandoned on a number of grounds. The Greek author deals with a very limited group of objects, namely those found in the 103 chamber tombs at Myceane excavated by Tsountas in 1887-89, including a few amber beads, all of the same shape. 14 Thus her types do not include many common shapes of amber beads, such as plane-convex or any type with rounded or beveled edges. Moreover, amber beads differ from those of most other materials in that they are often highly unsymmetric and irregular to take maximum advantage of the raw material from which they were carved, and in that originally angular shapes may become rounded by wear and weathering of the soft and reactive fossil resin. 15 Xenaki-Sakellariou shows only a single view of prolate and ob­ late beads and describes the latter (her Type 53) "ellipsoid, bi­ convex" (£A.A.wvon8fl<;, UJl) 1578 Pylos/Routsi necklace Bead NMA 8356 biconvex d. 19 th. 9 [GR]26A Baltic amber g: 1579 Pylos/Routsi necklace Bead 4 NMA 8356 [GR]26B Baltic amber ("D 1580 Pylos/Routsi necklace Bead 6 NMA 8356 [GR]26C Baltic amber (') ...... 1581 Pylos/Routsi necklace Bead 9 NMA 8356 [GR]26D unidentifiable c (/') 1582 Pylos/Routsi necklace B&ad 14 NMA 8356 [GR]26E Baltic amber i=d c 1583 Pylos/Routsi necklace Bead 20 NMA 8356 [GR]26F Baltic amber ~ s 1584 Pylos/Routsi necklace Bead 21 NMA 8356 [GR]26G Baltic amber 1:;1:1 s t:I:1 $>) 1585 Pylos/Routsi necklace Bead 24 NMA 8356 truncated bicone d. 52.5 th. 18 [GR]26H Baltic amber (') "1 1586 Pylos/Routsi necklace Bead 2 5 NMA 8356 [GR]261 Baltic amber ~ '< 0 1587 Pylos/Routsi necklace Bead 30 NMA 8356 [GR] 26J Baltic amber > ...... 1588 Pylos/Routsi necklace Bead 33 NMA 8356 [GR]26K ll\lltic amber z $>) 15B9 Pylos/Routsi necklace Bead 36 NMA 8356 [GR]26L Baltic amber 0 s 1590 Pylos/Routsi necklace Bead 41 NMA 8356 [GR]26M Baltic amber 1:""' 0"' ......
