Two lexicons resulted from our projects: a dictionary from the GEOANATOMY project and reference list from the TRANSIENTS project; both are continuously updated. The dictionary links Ancient Greek and Latin vocabulary (Utrecht) with modern science explanations. The results of the (previous) project in astronomy and astrophysics (Jena) is a reference list on identifications of historical transients that have been considered unclear and could refer to either novae, or supernovae, or comets.
