Julius Caesar Scaliger (or Giulio Cesare della Scala) (April 23, 1484 – October 21, 1558) is an Italian scholar and physician spending a major part of his career in France.
He employs the techniques and discoveries of Renaissance humanism to defend Aristotelianism against the new learning.
In spite of his arrogant and contentious disposition, his contemporary reputation is high, judging him so distinguished by his learning and talents that, according to Jacques August de Thou, none of the ancients could be placed above him, and the age in which he lived could not show his equal.
