"The Coronation of King Wilhelm at Königsberg" is the great and triumphant title-page to this section of his art. The effects of light, the red tones of the uniforms, the shimmering white silk dresses, the surging of the mass of people, the perfect ease with which all the personages are individualised, the princes, the ministers, the ambassadors, the men of learning, the instantaneousness in the movement of the figures, the absolutely unforced and yet subtle and pictorial composition, render this painting no picture of ceremonies, in the traditional sense of the phrase, but a work of art at once intimate and august in the impression which it makes. In the picture "King Wilhelm setting out to join the Army"--the representation of the thrilling moment, on the afternoon of 31st July 1870, when the King drove along the linden avenue to the railway station--this phase, which he began with the Coronation picture, was brought to a close. Everything surges and moves, speaks and breathes, and glows with the palpitating life which vibrates through all in this moment of patriotic excitement. But the painter's course led him further.
He first became entirely Menzel when he made the discovery of toiling humanity. In 1867, in the year of the World Exhibition, he came to Paris and became acquainted with Meissonier and Stevens. With Meissonier in particular--whose portrait he painted--he entered into a close friendship, and it was curious afterwards to see the two together at exhibitions--the little figure of Menzel with his gigantic bald forehead and the little figure of Meissonier with his gigantic beard, a Cyclops and a Gnome, two kings in the realm of Liliput, of whom one was unable to speak a word of German and the other unable to speak a word of French, although they had need merely of a look, a shrug, or a movement of the hand to understand each other entirely. He also came into the society of Courbet, who had just made the famous separate exhibition of his works, at the Café Lamartine, in the company of Heilbuth, Meyerheim, Knaus, and others. Here in Paris he produced his first pictures of popular contemporary life, and if as an historical painter he had already been a leader in the struggle against theatrical art, he became a pioneer in these works also. Everywhere he let in air and made free movement possible for those who pressed forward in his steps. In the course of years he painted and drew everything which excited in him artistic impulse upon any ground whatever, and not one of these endeavours was work thrown away. A universal genius amongst the painters of real life, he combined all the qualities of which other men of excellent talent merely possessed fragments separately apportioned amongst them: the sharpest eye for every detail of form, the most penetrative discrimination for the life of the spirit, and at times a glistening play of colour possessed by none of his German predecessors.
