Is there a Latin idiom for preparing for work? In English one can roll up one's sleeves, and the corresponding expression has the same meaning in Finnish. I doubt a direct translation of this idiom works in Latin, especially classical Latin, since sleeves were not as common in antiquity as they are today.
If you can suggest an idiom, please indicate if it is related to a specific kind of work or has other context restrictions. I prefer classical Latin, but also later expressions are welcome. If your suggestion is not attested in literature, please explain why it is good.
