Frumentius of Carthage (the second)
merchant and martyr in Vandal Africa
Feast: 23 March (not on the universal Roman calendar; kept in the Roman Martyrology or local calendars)
Who they were
Commemoration of the holy martyrs Victorian, proconsul of Carthage, in present-day Tunisia, two brothers from present-day Henchir-Baboucha, and two merchants both named Frumentius, who, during the Vandal persecution under the Arian king Huneric, were tortured with dreadful torments for persevering in the Christian faith and so received the glorious crown.
The miracles
There was never a formal cause: he has been honoured as a saint since before the Church's formal processes began.
Why that counted as sanctity
The Roman Martyrology remembers him on 23 March as the second of two merchants named Frumentius tortured under the Vandal king Huneric for persevering in the Christian faith.
