These two monarchs, although called to clash at various times, consolidate their respective empires politically and economically.
Justinian  already had in 519, under the reign of Justin I, worked for the reunification of the churches of the old and the new Rome (Rome and Byzantium).
His management of the crisis puts an end to the turbulence of the empire auguring a stable reign for Justinian. As a symbol of this reign, Saint Sophia is rebuilt. This inner stability allows Justinian to consolidate his empire.
(extract of the psalm 74 associated to this generation, verses 1 and 2 )
- A maskil of Asaph. Why, O God, have You forsaken forever? [Why] is Your wrath kindled against the flock of Your pasture?
- Remember Your congregation, which You acquired from time immemorial; You redeemed the tribe of Your heritage, Mount Zion on which You dwelt.
- The splendor  of the church (Saint Sophia) was not limited to its decoration: its architecture even seemed a miracle to its first visitors. For most of them, the most magical element was the extraordinary cupola, thirty-two meters in diameter, fifty-eight feet above the ground, larger and higher than all the others, a thin shell pierced with forty windows at its base so that it seems “suspended in the sky by a chain of gold”. Do not forget the furniture: the iconostasis of nearly twenty meters in sterling silver, the altar inlaid with gold and precious stones, the huge circular ambulatory for priests, illuminated by polychrome marble and mosaics, countless gold lamps. The relics were also more precious than those of all other churches, starting with the True Cross that had been brought back from Jerusalem, along with other instruments of the Passion, the Empress Helen. There were also swaddling clothes of Jesus and the table where the apostles had surrounded him for the Last Supper. It is hardly surprising that Justinian, entering the building for the first time on December 27, 537 – five years, ten months, and four days after laying the foundation stone – remained silent for a long time before whispering, ” Solomon, I have surpassed you. “
- The procession  [in 534, at Constantinople to celebrate the victory of Belisarius at Carthage on the Vandals] continued with a succession of wagons carrying the war chest. Including the Menorah, the seven-branched sacred candelabrum of which the Emperor Titus had seized in Jerusalem in the year 71 at the Temple of Jerusalem to carry it to Rome. Genseric had taken it in 455 to take it to Carthage. (Later on the request of representatives of the Jewish community, Justinian sent her back to Jerusalem with other liturgical objects of the Temple)
(extract of the psalm 74 associated to this generation, verses 3 and 4 to 10 )
- Raise Your blows to inflict eternal ruin, for all the evil that the enemy did in the Sanctuary.
- Your adversaries roared in the midst of Your meeting place; they made their signs for signs.
- Based on these observations, the following of the psalm marks the impatience of Assas when the fate of the Jewish people who suffered the attack of the nations during the whole half of the night and which probably will have to continue to undergo them during the second part of the night:
- May he be known as though bringing [their blows] on high; the hatchets were in the thicket of the trees.
- And now, its entrances together, with hatchets and hammers they strike.
- They set Your Sanctuary afire; to the ground they profaned the dwelling place of Your name.
- They said in their heart, their rulers together; they burned all the meeting places of God in the land.
- We have not seen our signs; there is no longer a prophet, and no one with us knows how long.
- How long, O God, will the adversary blaspheme? Will the enemy disgrace Your name forever?
