:::::::::::: It is true that there are Einstein biographers who claim that he invented relativity from pure thought, without attention to experiment. But it is not true that mathematical theory came first. Relativistic mass was already being tested in 1901, before Einstein. All of the original relativity papers cited experimental evidence. Eg, Minkowski said relativity was "grown on experimental physical grounds".
