Piranesi's Initials - a source of modern sans serif typography, were identified on the Plan of Nero's Nimphum (Fig.II and Fig.III). They were engraved in 1756 for Le Antichit Romane Tom.I [Plate] XLI when his Roman architectural authority was under threat within the Grco-Roman debate of the mid eighteenth-century. By adding serifs to the E [1] he argued that the ancient Italians added serifs to the primitive Archaic Latin alphabet [2] which took 21 letters used in the ETRVSCAN alphabet. The process involved the unneeded Zeta [3] which was moved to the end of the alphabet, and was replaced with Gamma [4] created from an Etruscan C. Then, following Romes conquest of Greece the Grca Y [5] was added to Classical Latin. V was used for U and the medieval ligatured double V became double-u [6]. Eventually a curled minuscule j became J and V became U following the post-Renaissance convention where I and U we're used as vowels, and J and V as consonants [7].

These primitivist origins of our modernist Sans Serif types were presented at ATypI18 in Antwerp the leading international conference on typography and type design, alongside the new emfoundry proto-sans font ETRVSCA (fka. Fount1756). 

Piranesi's decorative [NER]ONIONIANA initial majuscules are included in the regular and bold weights of the ETRVSCA Sans font family. This alphabet deliberately represents a Latin 'G' derived from the Etruscan 'C' glyph.
