Garum?

Edit: Okay, saw your other comment here:
Asafoetida (called hing in Hindi) is an interesting spice. I think it is a resin of some kind. It is used a fair amount in Indian cuisine.
Presumably, the person altering the recipe knew what the old version tasted like, so while it won't necessarily be authentic, I think it's probably better than the wild guesses made during translation of actual ancient recipes.
We have absolutely no problem translating the original recipes, which are in Latin. The only ambiguity is in ingredient quantities and cooking times, but any competent cook is able to figure those out.
The complete text (in Latin) of Apicius's De Re Coquinaria is here: http://users.ipa.net/~tanker/apicius.htm
In addition to Apicius, there are recipes in De Agri Cultura by Cato.
(edit: I mean, I already drink a lot of malt-forward lightly-hopped beers like scotch ales, sweet stouts, and bocks, but I really want to try a beer with no hops at all)
