Tell me where is fancy bred, Or in the heart or in the head? How begot, how nourished? Reply, reply. It is engender'd in the eyes, With gazing fed; and fancy dies ...

 

[Aprial.L]

This is a little poem from Sharkespeare, talking about love grew from eyes and fed by gaze.
I think in this sentence 'bred' is the past participle of 'breed', used as the adverbial of 'fancy' which means love in here.
so, i think this setence means 'where is love happened'.

Where is love born? What makes love happen?
