1) Agite porro, limaces! 2) Lente quoque proceditur.
给这篇翻译加备注
Sentence nr. 1 can be reduced to "agite, limaces" (something like "go on, snails") if you go short of breath (while running) and have to say it anyway. Sentence nr. 2 means literally "you can also go slowly forward". It is a variation on a phrase by Julius Caesar.
