Jason Farr (Ph.D. candidate, IPCAA, University of Michigan), will present a paper on his ongoing research into the local tufo at Gabii - lapis Gabinus - and its exploitation by means of quarrying in the late republican and early imperial periods. Farr's dissertation research seeks not only to better understand this tufo type, but also to explore connections between the Gabine quarries and the construction industry in Rome and Latium. Farr's paper, "Lapis Gabinus: new evidence for quarrying at Gabii", will be presented in Rome at the ASMOSIA X (Association for the Study of Marble and Other Stones In Antiquity), conference. This international conference takes place in Rome, from 21 to 26 May 2012, and is hosted by the Università di Roma 'La Sapienza'. Farr's talk is scheduled to for 09.00am on 23 May in the session entitled "THEMATIC SESSION III: Provenance identification II: (other stones)". The conference website is here.
