For these reasons, he decided on commencing the business of historian. The composition of _Don Carlos_ had already led him to investigate the state of Spain under Philip II.; and, being little satisfied with Watson's clear but shallow Work on that reign, he had turned to the original sources of information, the writings of Grotius, Strada, De Thou, and many others. Investigating these with his usual fidelity and eagerness, the Revolt of the Netherlands had, by degrees, become familiar to his thoughts; distinct in many parts where it was previously obscure; and attractive, as it naturally must be to a temper such as his. He now determined that his first historical performance should be a narrative of that event. He resolved to explore the minutest circumstance of its rise and progress; to arrange the materials he might collect, in a more philosophical order; to interweave with them the general opinions he had formed, or was forming, on many points of polity, and national or individual character; and, if possible, to animate the whole with that warm sympathy, which, in a lover of Freedom, this most glorious of her triumphs naturally called forth.
In the filling-up of such an outline, there was scope enough for diligence. But it was not in Schiller's nature to content himself with ordinary efforts; no sooner did a project take hold of his mind, than, rallying round it all his accomplishments and capabilities, he stretched it out into something so magnificent and comprehensive, that little less than a lifetime would have been sufficient to effect it. This History of the Revolt of the Netherlands, which formed his chief study, he looked upon but as one branch of the great subject he was yet destined to engage with. History at large, in all its bearings, was now his final aim; and his mind was continually occupied with plans for acquiring, improving, and diffusing the knowledge of it.
Of these plans many never reached a describable shape; very few reached even partial execution. One of the latter sort was an intended _History of the most remarkable Conspiracies and Revolutions in the Middle and Later Ages_. A first volume of the work was published in 1787. Schiller's part in it was trifling; scarcely more than that of a translator and editor. St. Réal's _Conspiracy of Bedmar against Venice_, here furnished with an extended introduction, is the best piece in the book. Indeed, St. Réal seems first to have set him on this task: the Abbé had already signified his predilection for plots and revolutions, and given a fine sample of his powers in treating such matters. What Schiller did was to expand this idea, and communicate a systematic form to it. His work might have been curious and valuable, had it been completed; but the pressure of other engagements, the necessity of limiting his views to the Netherlands, prevented this for the present; it was afterwards forgotten, and never carried farther.
