He was born in Huesca and became a deacon of the church of Saragossa (Zaragoza). He was tortured to death in Valencia, in the persecution of Diocletian. After his death, his cult spread rapidly through the Roman Empire. See the article in Wikipedia.

Fulgentius was bishop of the city of Ruspe in the Roman province of Africa, which is in modern-day Tunisia. At that time Africa and parts of the Near East were ruled by the Vandals, who were Arians, calling themselves Christians but denying the divinity of Christ. As a result Fulgentius’ early career was marked by a series of flights from persecution, as Catholics tried to maintain their faith under Vandal rule. It was a complicated time. In 499 he was tortured for saying that Jesus was both God and man; the next year the Vandal king Thrasamund, impressed by his talents, invited him to return from exile and become a bishop (Fulgentius declined, since he knew that Thrasamund had ordered that none but Arians should be bishops); two years later he was persuaded to become bishop of Ruspe in Tunisia but shortly afterwards he was exiled to Sardinia. Thrasamund invited him back in 515 to debate against the Arians but exiled him again in 520.

The theological virtue of hope is symbolized by the colour green, just as the burning fire of love is symbolized by red. Green is the colour of growing things, and hope, like them, is always new and always fresh. Liturgically, green is the colour of Ordinary Time, the orderly sequence of weeks through the year, a season in which we are being neither single-mindedly penitent (in purple) nor overwhelmingly joyful (in white).
