Pepys was an enthusiastic playgoer, and the _Diary_ contains a mass of information respecting the Stage not elsewhere to be found, so that we are able to trace the various advances made in the revival of the Stage from the incipient attempt of Davenant before the Restoration to the improvements in scenery introduced by the rivalry of the two managers, Davenant and Killigrew. Immediately after the Restoration two companies of actors were organized, who performed at two different houses. One theatre was known as the King's House, called by Pepys "The Theatre," and the other as the Duke's House, called by Pepys "The Opera." Sir William Davenant obtained a patent for his company as "The Duke's Servants," named after the Duke of York, and Thomas Killigrew obtained one for "The King's Servants." Killigrew's Company first performed at the "Red Bull," Clerkenwell, and on November 8th removed to Gibbons's Tennis Court in Bear Yard, which was entered from Vere Street, Clare Market. Here the Company remained till 1663, when they removed to Drury Lane Theatre, which had been built for their reception, and was opened on May 7th. Davenant's Company first performed at the Cockpit, Drury Lane. They began to play at Salisbury Court Theatre on November 13th, 1660, and went to Cobham House, Blackfriars, on the site afterwards occupied by Apothecaries' Hall, in January, 1661. They then removed to the theatre in Portugal Row, built on the site of Lisle's Tennis Court. Rhodes, a bookseller, who had formerly been wardrobe keeper at the Blackfriars, had managed in 1659 to obtain a licence from the State, and John Downes affirms that his company acted at the Cockpit, but apparently he was acting at the Salisbury Court Theatre before Davenant went there. Killigrew, however, soon succeeded in suppressing Rhodes. Davenant planned a new building in Dorset Gardens, which was close to Salisbury Court, where the former theatre was situated. He died, however, before it was finished, but the company removed there in 1671, and the theatre was opened on the 9th of November with Dryden's play, _Sir Martin Mar-all_, which he had improved from a rough draft by the Duke of Newcastle. Pepys had seen it seven times in the years 1667-68. The Lincoln's Inn Fields Theatre remained shut up until February, 1672, when the King's Company, burnt out of Drury Lane Theatre, made use of it till March, 1674, by which time the new building in Brydges Street, Covent Garden, was ready for their occupation. When Tom Killigrew died in 1682 the King's and the Duke's companies were united, and the Duke's servants removed from Dorset Gardens to Drury Lane. The two companies performed together for the first time on November 16th.
