Meroitic Cursive is the most widely attested script, comprising ~90% of all inscriptions, and antedates, by a century or more, the earliest, surviving Meroitic hieroglyphic inscription. Greek historian Diodorus Siculus (ca. 50 BC) described the two scripts in his Bibliotheca historica, Book III (Africa), Chapter 4.
Insular script was a medieval script system originating from Ireland that spread to Anglo-Saxon England and continental Europe under the influence of Irish Christianity. Irish missionaries took the script to continental Europe, where they founded monasteries such as Bobbio .
