Dome from below

In the centre of the transept, under the dome, the ceiling features pictures of the four great prophets, each one arranged in a corner of the structure, as if to signify their role as foundations of the cathedral heart: they are the carriers of the eternal Word of God, announcers of the great mysteries which sustain the Church’s faith.
Isaiah is the prophet who announces: “The Lord himself will give you a sign. The virgin will conceive and give birth to a son, and will call him Immanuel “(Is. 7, 14).
A strong and clear reference to Mary, the Virgin who gives birth to the Son of God.
Baruch offers a magnificent reflection-praise on Wisdom. It urges the People of Israel to consider what an extraordinary privilege God has given them by giving them His wisdom (cf.. Ba. 3, 37-38. 4.1). Is the announcement of the coming of Jesus in the world, the eternal Wisdom of the Father that puts his dwelling amongst men. Mary is, par excellence, the “location of Wisdom”: she welcomed Wisdom first with faith and then with her own body.
Joel is considered the prophet of Pentecost.
In the Pentecost day, St Peter Apostle proclaims the outpouring of the Spirit, quoting Joel’s prophecy: prophecy which is fulfilled precisely with the descent of the Holy Spirit and by the signs that accompany and follow it (cf. Acts 2, 16 -21).
Even Mary, together with the Apostles, receives the gift of the Holy Spirit who, however, has already worked in her in the mystery of the incarnation of God’s Word.
Hosea is the first of the prophets who dared to make the conjugal love the symbol of God’s love for Israel, His people.
Hosea comes to this symbolism reflecting on his personal experience, that of an unhappy marriage, a betrayed love.
Through this consideration, Hosea understands the mission that God entrusts him: being cantor and interpreter of the bridal love between God and Israel: the tender and merciful love of God, which is constantly, tirelessly faithful. That Love that God gives to mankind in the person of Jesus, passing through the Virgin Mary
