Advances into the origins of monetisation in the Mediterranean have shown that even with state-controlled currency circulating, (coinage-less) credit economies existed in parallel, using written documents for transactions, well into the Roman period. The current paper documents that a credit economy facilitated the Phoenician commercial expansion in the Mediterranean (9th-7thc. BCE), becoming the vehicle by which the west Semitic abjad, the Phoenician ‘alphabet’, was rapidly adopted and adapted into various phonetic and syllabic scripts in the Mediterranean. This led to the rapid spread of literacy in societies that had been fully illiterate by then, as the Greeks, or that had never developed literacy. In contrast with previous explanations that saw the spread of literacy in the Mediterranean as a corollary to international trade, the present study postulates that literacy played a functional role within the credit economies that grew with international commerce, thereby providing the impetus for the spread of literacy, providing documentation that substantiates this hypothesis. The study links the rapid spread of literacy to the institutional role of the script within the context of monetised commercial transactions, utilizing archaeological evidence from both ends of the Mediterranean, and interpreting it within its historical context.

Dois dos problemas mais importantes e fundamentais na pesquisa proto-histórica e antropológica são relacionados à popularização da alfabetização e às origens do dinheiro. As razões por trás da propagação repentina e abrangente do alfabeto fenício no século VII1,VII a.C. permanecem sem solução, apesar dos debates contínuos. Ao mesmo tempo, permanece largamente ignorado na pesquisa acadêmica o paradoxo de que os fenícios, comerciantes da antiguidade por excelência, aparentemente náo usaram nenhuma forma de moeda física, apesar de possuírem redes comerciais no Mediterrâneo. No entanto, pesquisas recentes suportam o alto grau de monetização das redes comerciais fenícias, bem como o fato de que formas de "proto-moeda" circulavam no Levante pelo menos a partir do século VI11 a.C. Este artigo pretende analisar esses dois problemas de uma perspectiva totalmente nova, explorando os vínculos entre eles e testando se uma causalidade pode ser estabelecida entre a repentina divulgação da alfabetização e a ausência de moeda física na economia fenícia, com foco no Ocidente. E sugerido que o aumento da monetização foi possível através dos padrões de intercâmbio comercial estabelecidos no Próximo Oriente desde o terceiro milênio a.C., que permitiram transações usando letras de crédito (notas promissórias), com pagamentos eventuais efetuados em vários meios através de um índice estabelecido de valor (por exemplo, relativo à prata).

The study departs from recent suggestions that locally produced balance weights from settlement sites in central Portugal, dated to the Final Bronze Age (1200-900 BCE) are based on a Late Bronze Age Syrian/Ugaritic metrological system (13th-12th c. BCE). These proposals have been based on the comparative studies of the weights of these Atlantic objects, but have not been examined rigorously in comparison with Near Eastern metrological systems, despite the claims they make. This has repercussions for the conclusions drawn so far. The present study has a threefold aim. First, it examines this hypothesis of a Syrian derivation of metrological systems underlying the local production of balance weights in Atlantic Iberian settlements (ca. 1200-900 BCE). Secondly, it investigates whether these local balance weights bear any metrological relationship to the balance weights of Phoenician typologies encountered in Atlantic Iberian sites of the colonial period (8th-6th c. BCE). Thirdly, taking as a case study the better documented evidence from Alcácer do Sal, it examines for the first time whether these metrological systems, in use for centuries in Atlantic Iberia, underly the metrologies of the earliest, pre-Roman, locallyminted coinage, which follows Phoenician iconography but is struck using the syllabary of the indigenous languages, developed in the 8th c. BCE as an adaptation of the Phoenician script. The study suggests that the dating of the earliest group of balance weights needs to be lowered. In addition, it documents a likely derivation of the metrological system of coinage from the Phoenician milieu of Iberia, rather than the 3rd c. BCE Carthaginian metrologies, as advocated so far. This is supported by the metrological continuity between balance weights and coinage, and the latter's iconography, as the present study documents.
