"Beck"

Nicholas Breton-"A Wanton Woman"-BA, 16
"Her beck is a net"

The footnote says that a beck (according to the OED) is an "inviting look or signal." A Wanton Woman is a great seductress and her beck is one of her ways to entice. It is similar to how a wife looks at her husband a certain way...and he knows what that look means! Her beck will capture the seeker like a "net" and not let go of the prisoner caught in it.

Breton ultimately describes this "beck" and the "wanton woman" as evil, and these should be avoided unless the seeker wants to be corrupt like the seductress already is.
