 After Cosimo 's triumphant return to Florence , rather than scrapping the project , in May 1436 the Medici regime hired Uccello to replace the Gaddi and <unk> fresco . Hugh Hudson suggests that it would have been too risky for the Medici to cancel the Albizzi project , so they instead shrewdly modified it to fit their interests . There is , of course , some weakness to attributing the commissioning and re @-@ commissioning of the monument to Albizzi or Medici intrigues , as only two ( maybe three ) of the eight operai on July 13 , 1433 were members of the Albizzi faction and only one was a Medici when it was resumed on May 18 , 1436 ; yet the influences of both factions doubtlessly did not require blood relation . Around this time , documents attest to multiple repairs of a nearby window , opening the possibility that the original fresco had experienced water damage , and would have needed to be restored in any case . Others have suggested that the recommissioning was part of the " refurbishing " of the cathedral associated with its rededication as Santa Maria del Fiore by Pope Eugene IV in March 1436 . Yet , <unk> concludes that " undoubtedly under pressure from the Medici " the operai discarded their plans for a straightforward restoration of the Gaddi fresco and opted for a completely new monument .
