Premise: Local master artist Tintoretto (1518 1594) won a competition to create for the hall some 50 paintings (the largest collection of his work anywhere) over a period of 23 years, a series comparable in grandeur to Giotto's frescoes in Padua's Scrovegni Chapel or Florence's Brancacci chapel by Masaccio.

Hypothesis: The competition to decorate the hall was won by Franseco, narrowly beating Tintoretto. 
Relation: contradiction
