Our author’s next tragedy was upon the subject of Iphigenia, daughter to Agamemnon King of Argos, acted at the Theatre in Lincoln’s-Inn 1704. Iphigenia was to have been sacrificed by her father, who was deluded by the fraud of Calchas, who proclaimed throughout the Grecian fleet, that the offended gods demanded of Agamemnon the sacrifice of his daughter to Lucina, and till, that oblation was offered, the fleet would remain wind-bound. Accordingly, under pretence of marrying her to Achilles, she was betrayed from Argos, but her mother, Clytemnestra, discovering the cheat, by a stratagem prevented its execution, and effected her rescue without the knowledge of any one but her husband Agamemnon. A Grecian virgin being sacrificed in her place, Iphigenia is afterwards wrecked on the Coast of Scythia, and made the Priestess of Diana. In five years time her brother Orestes, and his friend Pylades, are wrecked on the same shore, but saved from slaughter by the Queen of Scythia, because she loved Orestes. Orestes, on the other hand, falls in love with the Priestess of Diana; they attempt an escape, and to carry off the image of the Goddess, but are prevented. The Queen then dooms Orestes to the altar, but Pylades, from his great friendship, personates Orestes, and disconcerts the design. The story and incidents of this play are interesting and moving, but Mr. Dennis has not wrought the scenes much in the spirit of a tragedian: This was a subject admirably suited for the talents of Otway. The discovery of Orestes’s being the brother of Iphigenia is both surprizing and natural, and though the subject is not well executed, yet is this by far the most affecting tragedy of our author; it is almost impossible to read it without tears, though it abounds with bombast.
The fourth play introduced upon the stage by Mr. Dennis, 1704, was, a tragedy called Liberty Asserted, dedicated to Anthony Henley, esq; to whom he says he was indebted for the happy hint upon which it was formed. Soon after this he wrote another tragedy upon the story of Appius and Virginia, which Mr. Maynwaring, in a letter to Mr. Dennis, calls one of our best modern tragedies; it is dedicated to Sidney Earl of Godolphin.
