Roderic, Count of Saxe Weimar, a prince of tyrannical and licentious disposition, has for his Prime Minister and favourite, Gaspar, a crafty villain, who had risen to his post by first ruining, and then putting to death, Rogero's father. Gaspar, apprehensive of the power and popularity which the young Rogero may enjoy at his return to Court, seizes the occasion of his intrigue with Matilda (of which he is apprised officially by Doctor Pottingen) to procure from his master an order for the recall of Rogero from college, and for committing him to the care of the prior of the Abbey of Quedlinburgh, a priest, rapacious, savage, and sensual, and devoted to Gaspar's interests--sending at the same time private orders to the prior to confine him in a dungeon. Here Rogero languishes many years. His daily sustenance is administered to him through a grated opening at the top of a cavern, by the landlady of the Golden Eagle at Weimar, with whom Gaspar contracts, in the Prince's name, for his support; intending, and more than once endeavouring, to corrupt the waiter to mingle poison with the food, in order that he may get rid of Rogero for ever. In the meantime Casimere, having been called away from the neighbourhood of Matilda's residence to other quarters, becomes enamoured of, and marries Cecilia, by whom he has a family; and whom he likewise deserts after a few years' cohabitation, on pretence of business which calls him to Kamtschatka. Doctor Pottingen, now grown old and infirm, and feeling the want of his daughter's society, sends young Pottingen in search of her, with strict injunctions not to return without her; and to bring with her either her present lover Casimere, or, should that not be possible, Rogero himself, if he can find him; the doctor having set his heart upon seeing his children comfortably settled before his death. Matilda, about the same period, quits her aunt's in search of Casimere; and Cecilia having been advertised (by an anonymous letter) of the falsehood of his Kamtschatka journey, sets out in the post-waggon on a similar pursuit. It is at this point of time the play opens--with the accidental meeting of Cecilia and Matilda at the inn at Weimar. Casimere arrives there soon after, and falls in first with Matilda, and then with Cecilia. Successive _éclaircissements_ take place, and an arrangement is finally made, by which the two ladies are to live jointly with Casimere. Young Pottingen, wearied with a few weeks' search, during which he has not been able to find either of the objects of it, resolves to stop at Weimar, and wait events there. It so happens, that he takes up his lodging in the same house with Puddincrantz and Beefinstern, two English noblemen, whom the tyranny of King John has obliged to fly from their country; and who, after wandering about the Continent for some time, have fixed their residence at Weimar.
