Appendix Probi


The Appendix Probi is a palimpsest appended to the Instituta Artium, a work written in the 3rd or 4th century AD. The text survives only in a carelessly transcribed water-damaged manuscript of the 7th or 8th century. In the past, it was attributed to Valerius Probus, but that is now considered wrong. The surviving manuscript is believed to have been transcribed at Bobbio Abbey, and it is currently kept at the Biblioteca Nazionale Vittorio Emanuele III.
The Appendix lists common mistakes in the written Latin of the time. In those mistakes, tendencies in the grammar, spelling, and pronunciation of the contemporary vernacular can be observed that would become the various Romance languages. The author's corrections of the usages give us insight into how Latin was evolving at that time. For example, the instruction or tells the reader that the Classical Latin word is written with an at the end, which indicated nasalization. That common spelling error suggests that nasal vowels were being denasalized in Vulgar Latin. Many of the mistakes later became standard spelling: Spanish nunca, from . In some cases, the document recommends forms that are not the usual classical ones: recommends an, whereas amphora is normally spelled with.
The original location of composition of the Appendix is uncertain, but a few theories have been proposed by scholars. Some commentators identify North Africa as the place of composition: for instance, Gaston Paris suggests that the document may have been written in Carthage. Others argue that it was likely written in Rome, citing line 134,, as the name of a neighborhood in Rome. Reconciling the two views, Casimir Jarecki argues that the document is perhaps the work of a teacher born in Africa but living in Rome.
