THE RED BULL: "A PUBLIC PLAYHOUSE IN CLERKENWELL IN MIDDLESEX, SOME 575 YARDS NORTH OF THE CITY BOUNDARY AT SMITHFIELD. IT WAS BUILT IN AND AROUND THE YARD OF A FORMER INN THAT LAY BEHIND BUILDINGS ALONG THE WEST SIDE OF ST. JOHN STREET, AND ITS MAIN ENTRANCE WAS A PASSAGEWAY THROUGH THOSE BUILDINGS. ITS NAME WAS PROBABLY THAT OF THE INN. THE SITE IS CLOSSELY MARKED NOW BY THE EASTERN HALF OF HAYWARD'S PLACE E.C. 1, WHICH ALSO BEGINS WITH A PASSAGEWAY THROUGH THE BUILDINGS ALONG THE WEST SIDE OF ST. JOHN'S STREET. THE MODEL FOR THE RED BULL MUST HAVE BEEN THE BOAR'S HEAD, WHICH HAD BEEN BUILD SIX YEARS BEFORE IN, AND NAMED FOR, AN INN."
