[EN] We introduce Argos, an online search engine for Greco-Latin treebanks, developed by the Greek Linguistics Group at ILC (CSIC). Argos is designed as an intuitive and efficient tool, enabling complex searches and providing results in user-friendly formats, with future plans for expansion to incorporate more features and languages. To contextualize this tool, we present a brief overview of the state of the art in treebanks, focusing particularly on those dedicated to Ancient Greek and Latin, and their search engines.
