Theories of "Pre-Indo-European" languages in Europe are built on scant evidence. The Basque language is the best candidate for a descendant of such a language, but since Basque is a language isolate, there is no comparative evidence to build upon. Theo Vennemann nevertheless postulates a "Vasconic" family, which he supposes had co-existed with an "Atlantic" or "Semitidic" (i. e., para-Semitic) group. Another candidate is a Tyrrhenian family which would have given rise to Etruscan and Raetic in the Iron Age, and possibly also Aegean languages such as Minoan or Pelasgian in the Bronze Age.
