Thirty years of our pioneer article: D.Ivanenko, G.Sardanashvily, "The Gauge Treatment of Gravity", Physics Reports, 94 (1983) 1-45, where a gravitational field (a pseudo-Riemannian metric) is described as a classical Higgs field responsible for spontaneous breakdown of space-time symmetries in accordance with the geometric Equivalence Principle.
