Old Irish is thus forebear to Modern Irish, Manx, and Scottish Gaelic. - Wikipedia

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. - Wikipedia
