Studio Et Vigilantia

Here is today's emblem and distich by Gabriel Rollenhagen, Book 1.67, with an English rendering by George Wither. The printed book clearly reads sapientem there, but I've written sapientum here instead - I think it must be an error in the original, but if someone thinks otherwise, please let me know!

Studio Et Vigilantia
Qui vigili studio sapientum scripta volutat,
Hic dici doctus cur mereatur habet.

By Studie, and by Watchfulnesse
The Jemme of Knowledge, we possesse.

Here is the vocabulary:

studium - eagerness, zeal
et - and
vigilantia - wakefulness, watchfulness
qui - who, which, that
vigilis - wakeful, watchful; watchman
sapiens - wise; wise man
scribo - write
