On some later stele statues belonging to Group C, there are inscriptions engraved in the Etruscan alphabet, which have sparked interest but their interpretation remains uncertain. The type of alphabet used, including the typical “St. Andrew’s cross” sign with the dental sound “th,” is characteristic of inner and northern Etruria, as well as the Po Valley and Veneto regions. This type of script is dated to the late 6th century BCE.

The known inscriptions are three in number:

• “mezunemunius” (or “mezu nemunius”) on the statue stele of Zignago.
• “(u) vezaruapus” (or “vezaru apus”) is the inscription found on the statue stele of Filetto II.
• “vemetuvis” is the inscription found on the statue stele of Bigliolo.

Although the interpretation is uncertain, it is hypothesized that these inscriptions represent personal names expressed in a form composed of either a single element (“mezunemunius”) or two elements (“mezu nemunius”).
