Here's the opening of a Latin poem:
Quis multa gracilis te puer in rosa
perfusus liquidis urget odoribus
grato Pyrrha sub antro?
Here's what it looks like if you have perfect knowledge of the vocabulary involved: What many slender you boy in rose
soak liquid press odor
pleasant Pyrrha[a name] under cave?
Does that help you to read it? (Bear in mind that Latin and English are, unlike Chinese and Japanese, related to each other. You even got three words that are more or less identical in Latin and English! [In all three cases, as in the case of Sino-Japanese vocabulary, that's due to borrowing rather than a relationship between the languages. But you can also see a true cognate - Latin quis is in a real sense the same word as English what.])
