The primary information related to Mattan I comes from Josephus's citation of the Phoenician author Menander of Ephesus in Against Apion i.18. Here it is said that "Badezorus was succeeded by Matgenus his son: he lived thirty-two years and reigned, nine years: Pygmalion succeeded him".
Alternative dates for his reign, from 829 to 821 BC, are given in the work of F. M. Cross and other scholars who take 825 BC as the date of Dido's flight from her brother Pygmalion, after which she founded the city of Carthage in 814 BC. For those who place the seventh year of Pygmalion in 814 BC, i.e. in the same year that Dido left Tyre, the dates of Mattan and Pygmalion will be 11 years later.
