Premise: As a result of the painstaking centimeter-by-centimeter recovery of the fragmentary but still powerful traces of the real Leonardo, we can now see, for example, that Philip (third to the right) has an expression of acute grief rather than the simpering pathos left by restorers who presumed to improve on the original.

Hypothesis: The restoration effort uses state-of-the-art technology such as thermal imaging.
Relation: neutral
