 Compared to Classical Latin, written documentation of Vulgar Latin appears less standardized.Works written in Latin during classical times and the earlier Middle Ages used prescribed Classical Latin rather than Vulgar Latin, with very few exceptions (most notably sections of Gaius Petronius' "Satyricon"), thus Vulgar Latin had no official orthography of its own.By its nature, Vulgar Latin varied greatly by region and by time period, though several major divisions can be seen.
