I found this poem in the collection Philosophia Patrum edited by Julius Wegeler.
Vultus Fortunae
Vultus Fortunae mutatur imagine lunae;
Crescit, decrescit, in eodem sistere nescit.
The vocabulary is keyed to the DCC Latin Vocabulary list. There are two words in this poem that are not on the DCC list:
dēcrescō, dēcrescere: decrease, diminish
sistō, sistere: stop, stand
crēscō crēscere crēvī crētum: grow, increase
fortūna -ae f.: fortune
īdem eadem idem: the same
imāgo -inis f.: image, form, figure
in: in, on (+ abl.); into, onto (+ acc)
lūna -ae f.: moon
mūtō -āre: change
nesciō -scīre: not know, be ignorant
vultus -ūs m.: look, expression, face
