Note 15 — ACT II.
Reading edition
I suppose he means a bumper, a cup filled till the wine rises above the top of it. Such a character as Dotterel is hardly made to allude to the pocula coronata of the Romans.—Steevens.
A crowned cup was not an unusual expression for a bumper: thus, in "All Fools," Fortunio says—
"True, and to welcome Dariotto's lateness He shall (unpledg'd) carouse one crowned cup To all these ladies' health."
Dotterel might therefore very properly employ words in ordinary use, without supposing him acquainted with "the pocula coronata of the Romans."—Collier.
