Encouraged by this invitation, d'Artagnan followed the duke, who closed the door after them. The two found themselves in a small chapel covered with a tapestry of Persian silk worked with gold, and brilliantly lighted with a vast number of candles. Over a species of altar, and beneath a canopy of blue velvet, surmounted by white and red plumes, was a full-length portrait of Anne of Austria, so perfect in its resemblance that d'Artagnan uttered a cry of surprise on beholding it. One might believe the queen was about to speak. On the altar, and beneath the portrait, was the casket containing the diamond studs.
