The Maltese islands are renowned for their prehistoric archaeological record, particularly thefamous megalithic ‘temples’ and associated ceramics and artwork. The temples were built bya society lacking metal technology, who relied on stone and organic materials. Knapped stonetool (lithic) technology, to produce sharp edged tools for tasks like cutting, hide working, andwood shaping involved the use of both imported obsidian and high-quality chert – offeringinsights into themes of exchange and connectivity – and local chert. The local chert hasgenerally been described as low-quality, yet relatively little research has been conducted on its distribution, characteristics, and use. In this paper I report a survey of chert sources, identifying a wider distribution of chert outcrops along the west coast of Malta than previously discussed. Some general macroscopic properties are outlined, while there are also aspects of variability in the chert sources. Knapping experiments were then conducted on samples of chert collected, allowing clarification of its characteristics. These observations are used to offer some insightsinto lithic technology in Neolithic and Temple Period Malta, such as the hypothesis that the high frequencies of multidirectional flake production and subsequent ‘scraper retouch’ reflect adaptations to the characteristics of local chert.
