Roman authors, such as Sallust, allude to some books written in the Punic language, but none have survived except occasionally in translation (e.g., Mago's treatise) or in snippets (e.g., in Plautus' plays). The Cippi of Melqart, a bilingual inscription in Ancient Greek and Carthaginian discovered in Malta in 1694, was the key which allowed French scholar Jean-Jacques Barthélemy to decipher and reconstruct the alphabet in 1758. Even as late as 1837 only 70 Phoenician inscriptions were known to scholars. These were compiled in Wilhelm Gesenius's "Scripturae linguaeque Phoeniciae monumenta", which comprised all that was known of Phoenician by scholars at that time.
