Theodora 1 respected him even after his death, remembering his noble deeds and wanting to neglect none of his decisions - but she failed; hence most of his achievements were destroyed

As Michael 61 put on the divine habit shortly before Monomachos' death, many people surmised Michael 61's thinking - that he knew this was the moment and retired for that reason
Despairing of life he lay like a sacrificed ox longing to die, but did not consult Theodora 1 about the future: hiding his plan from her he secretly sought a successor; but his plan could not remain secret and was reported to Theodora 1

He died at Constantinople, and Theodora 1 was chosen in his place
. Anonymus Barensis 152
He died unwillingly, lying sick and alone for a little before death, essentially having lost the empire, abandoned by all his family, since everybody had passed over to the side of Theodora 1, who did not spend timne with him
Psellos Keroularios 357
He died, sent swiftly to the tomb by the abominable gout
παλαμναῖαι νόσοι. Manasses, Chronicle 6224-6227a
He fell sick and died, in circumstances of which Michael 61 says nothing; save that the event seems to take place between the moment when he gave the sick Psellos leave to go to Olympos and the moment of his departure
Psellos Xiphilinos 421
He was distressed to hear of Theodora 1's return and his illness increased; as he could neither recover nor make an intelligent plan, he plunged into thought, closed his eyes and his mind and tongue strayed
When Theodora 1's proclamation became known to him it increased his suffering; after living on for a short time, enough to grieve and be dismayed at events, he departed, after being emperor for twelve years
Zonaras 17.28.21
When he departed life, the power passed to Theodora 1
