The topic of the first colloquium of Luwian Studies was: “What do we know about Luwian – and how do we know that?” On 3 November 2016, twenty experts from different European countries met in Zurich to exchange their views under the moderation of Alice Mouton (Paris). Each of the lectures by Annick Payne (Bern), Frederico Giusfredi (Verona), Ilya S. Yakubovich (Marburg) and Massimiliano Marazzi (Naples) was followed by extensive discussions in a very collegial atmosphere. It was possible to explore both the similarities as well as the divergences. The speakers and organizers are in agreement that the proceedings of the colloquium including the discussions should be published as soon as possible. The work has already begun.
