Note 41 — ACT II.
Reading edition
“This alludes to a scene in the tragedy of Mulleasses the Turke, 1610, by Mason, where Borgias appears as a ghost, and is addressed by Mulleasses in these words:—
‘Illusive ayre, false shape of Borgias, Could thy vaine shadow worke a feare in him That like an Atlas under went the earth, When with a prim and constant eye he saw Hell’s fifty-headed porter; thus I’d prove Thy apparition idle. [Runnes at Borgias. Borg. Treason! I live.’”—Reed.
