Paulatim, Non Impetu

Here is today's emblem and distich by Gabriel Rollenhagen, Book 1.49, with an English rendering by George Wither. As you can see in the emblem, the tiny bit of sand - harenula - in the poem is the sand of the hourglass. The sand runs down in a slow but steady stream, not all in a rush.

Paulatim, Non Impetu
Paulatim leni decurrit arenula lapsu,
Non impetu delabitur.

What cannot be by Force attain'd,
By Leisure, and Degrees, is gain'd.

Here is the vocabulary:

paulatim - slowly, bit by bit
non - not, no
impetus - attack, assault, charge
lenis - gentle, light
decurro - run down, race to
harena - sand
delabor - slip, slide down
