Morton, who was one of the accomplices, assembled a large force of his followers, consisting, it is said, of five hundred men, which he posted in the evening near the palace, and when it was dark he moved them silently into the central court of the palace, through the entrance E, as marked upon the following plan.

Description.
Apartments.

Mary was, at the time of these occurrences in the little room marked C, which was built within one of the round towers which form a part of the front of the building, and which are very conspicuous in any view of the palace of Holyrood.[G] This room was on the third floor, and it opened into Mary's bed-room, marked B. Darnley had a room of his own immediately below Mary's. There was a little door, d, leading from Mary's bed-room to a private stair-case built in the wall. This stair-case led down into Darnley's room; and there was also a communication from this place down through the whole length of the castle to the royal chapel, marked Ch, the building which is now in ruins. Behind Mary's bed-room was an ante-room, R, with a door, o, leading to the public stair-case by which her apartments were approached. All these apartments still remain, and are explored annually by thousands of visitors.

Morton and Ruthven.

It was about seven o'clock in the evening that the conspirators were to execute their purpose. Morton remained below in the court with his troops, to prevent any interruption. He held a high office under the queen, which authorized him to bring a force into the court of the palace, and his doing so did not alarm the inmates. Ruthven was to head the party which was to commit the crime. He was confined to his bed with sickness at the time, but he was so eager to have a share in the pleasure of destroying Rizzio, that he left his bed, put on a suit of armor, and came forth to the work. The armor is preserved in the little apartment which was the scene of the tragedy to this day.
