One or two Daniil’s trips to Kyiv?

Nicholas Zharkikh

Shortened text of the section. Full text in ukrainian version.

O. Tolochko expressed doubts about the reality of Daniil’s campaign to help Volodymyr Rurikovich against Michael, considering it a doubling of the story about the campaign of 1234.

The principle proposed by O. Tolochko can be expressed by a formula

1 = 0,

and in this form its fallibility becomes quite obvious. And this formula is not only a metaphor! Information has a quantitative dimension, and it is studied by such a branch of mathematics as information theory, and zero in any case means the absence of information.

As for the mentioned campaigns, the critic himself cannot invent motives for doubling the entry, and therefore it is better to leave the text as it is, that is, with two campaigns.
