As he approached the tribune he uncapped, a thought on the near side of self-abasement, to his brother, whose cavalier acknowledgment of the salute halted him, however, affable and smiling, on the lowest step of the dais. He was studious, while there, to inform with the right touch of pleasant condescension (at least while Galeazzo’s regard was fixed on him) his attitude towards Simonetta, lest the ever-suspicious mind of the tyrant should discover in it some sign of a corruptive intimacy. With heirs-possibly-presumptive in Milan, sufficient for the day’s life must be the sleepless diplomacy thereof; and better than any man Ludovico knew on what small juggleries of the moment the continuance of his depended. His complexion being of a swarthiness to have earned him the surname of The Moor, he had acquired a habit of drooping his lids in company, lest the contrastive effect of white eyeballs moving in a dark, motionless face should betray him to the subjects of those covert side-long glances by which he was wont to observe unobserved. Even to his shoulders, which were slightly rounded by nature, he managed, when in his brother’s presence, to give the suggestion of a self-deprecatory hump, as though the slight burden of State which they already endured were too much for them. His voice was low-toned; his expression generally of a soft and rather apologetic benignity. His manner towards all was calculated on a graduated scale of propitiation. Paying every disputant the compliment of deferring outwardly to his opinions, he would not whip so little as a swineherd without apologising for the inconvenience to which he was putting him. His dress was rich, but while always conceived on the subdominant note, so to speak, as implying the higher ducal standard, was in excellent taste, a quality which he could afford to indulge with impunity, since it excited no suspicion but of his simplicity in Galeazzo’s crude mind. In point of fact Messer Ludovico was a born connoisseur, and, equally in his choice of men, methods, and tools, a first exemplar of the faculty of selection. Presently, seeing the Duke’s gaze withdrawn from him, he spoke to Messer Simonetta more intimately, but still out of the twisted corner of his mouth, while his eyes remained slewed under their lids towards the throne:— ’Indeed, my lord, indeed yes; ’tis a veritable Castalidis, fresh from Parnassus and the spring. Tell me, now—’tis no uncommon choice of my brother to favour a fair boy—what differentiates this case from many?’ The secretary, long caged in office, and worn and toothless from friction on its bars, had yet his ideals of Government, personal as well as political. ’Your Highness,’ said he, in his hoarse, thin voice, ’what differentiates sacramental wine from Malvasia?’ ’Why,’ answered Ludovico, ’perhaps a degree or two of headiness.’ ’Nay,’ said the secretary, ’is it not rather a degree or two of holiness?’
