Bipolar Technique - Production, Products and Function of Lithic Artefacts

Kind of Event

IX Incontro Annuale di Preistoria e Protostoria

Genova – 4 Marzo 2021


1st circular

The use of bipolar technique on anvil is documented on a global scale, over a wide chronological span, from the Palaeolithic to Protohistory. Compared to the mainly typological approach of the last century, this technique and the characteristics of bipolar products have been broadly reconsidered thanks to the application of modern technological and functional analyses.

Over the last few decades bipolar knapping has been the subject of a vast interdisciplinary literature that has emphasized
the complex nature of artefacts commonly defined as “splintered pieces”, also highlighting the variety of applications of this technique. One of the main questions currently under discussion is whether the so-called "splintered pieces" are to be
considered as being merely more or less exhausted cores (therefore exclusively connected to the production of blanks), or can represent different categories of artefacts (wedges, tools...) that can also be distinguished on a morphological basis. In particular, research has focussed on the processing of organic and other materials, by the use of knapped lithic artefacts.

These tools a posteriori are known in the literature as pièces intermédiaires and can display traces possibly due to an
intentional façonnage, usually aimed at reducing the thickness of the blanks, whose purpose has been variously
interpreted. The versatility of bipolar technique and its considerable chronological and geographical diffusion (its use is widely known also in ethnography), poses problems that go beyond the strictly technological field to invest aspects of socio-economic behaviour, that can be investigated only by taking into account the different archaeological contexts.

The goal of the meeting will be twofold:
1) to provide an opportunity for comparison of the different study experiences and approaches adopted;
2) to promote a discussion on the "bipolar" topic with the aim of highlighting and defining the role of this component within the most diverse contexts. In particular, the meeting will focus on production methods, characteristics of products and function of knapped lithic artefacts, without neglecting the relevant methodological and terminological aspects.

Location: Dipartimento di Antichità, Filosofia, Storia - Università degli Studi di Genova.
Organization: depending on the number of proposals received, the Annual Meeting of Prehistory and Protohistory may take place in one or two days. It is therefore expected:
- 20-minute presentations to be selected by the Scientific Committee from the submissions.
- posters to be presented by brief oral overviews (5 minutes).

There will also be time allotted for discussion, the main objective of the meeting, inserting moments dedicated to the debate both at the end of the day and after each paper, trying to group the interventions on the basis of the topics addressed.

We do not plan to publish the Acts of the conference, only the volume of extended abstracts. The booklet of abstracts, in
addition to being distributed to participants during the meeting, will be available online on the IIPP website (

Calendar: The meeting will take place on Thursday, March 4, 2021 and, if necessary, will continue until the following day. Proposals for communication and posters are invited by 30 December 2020 at the latest, by sending a title and an abstract to the following e-mail address:

The abstract in Italian and English must be between 2000 and 4000 characters long (for each of the two versions) and
may include 1-2 images and up to a maximum of 5 bibliographical references. Please include the name of the author(s),
followed by affiliation, address and e-mail address.

Scientific Committee: Jacopo Conforti, Stefano Grimaldi, Adriana Moroni, Fabio Negrino, Giulia Ricci
