“I want to go about like the light-footed goats.”

Book of Taliesin (c. 1275?), The Fold of the Bards

As quoted in The Barbarian's Beverage: A History of Beer in Ancient Europe (2005) by Max Nelson, p. 28. In this epigram, Julian mocked the beer of the Germans and Celts as disgusting in comparison with wine.

Context: Who and from where are you Dionysus?
Since by the true Bacchus,
I do not recognize you; I know only the son of Zeus.
While he smells like nectar, you smell like a goat.
Can it be then that the Celts because of lack of grapes
Made you from cereals? Therefore one should call you
Demetrius, not Dionysus, rather wheat born and Bromus,
Not Bromius.

Context: We must face unconsidered possibilities and ask ourselves alarming questions–for instance, must we perhaps let the self-destroyer go if he really wants to? Trying to answer this by collecting information about our own neurones would be no more use than doing it, like the Roman augur, by inspecting the entrails of a goat.
