The inscription on the Pantheon in Rome displays formal capitals around the first century. Words in ancient Rome are often abbreviated and not separated by a space.
The word as we know it today, was not born yet.
The inscription reads: M[arcus] Agrippa L[ucii] f[ilius] co[n]s[ul] tertium fecit,” meaning ‘Marcus Agrippa, son of Lucius, made [this building] when consul for the third time.’
