Thanks ZM for bringing up the words "La Tène" and "Hallstatt" . Brings back our impressive Art history teacher:the great Mrs. Giacometti. Who took us from there through the ages of European Art. Juggling casually with migrating populations. She always wore a turban. What it stood for or hid none of us ever knew. Jokes and guesses.
She motherly invited first year male students who looked interesting and slightly underfed to plates of oatmeal porridge.
(No, let the dirty mind lobes sleep), that's all there was to it.
Oatmeal must be good, they got remarkably good marks.

(I've noted your book recommends)
