embowed

Il Penseroso": "But let my due feet never fail To walk the studious cloister's pale, And love the high embowed roof, With antique pillars massy proof, And storied windows richly dight, Casting a dim religious light.

On the west side the Rambler passes the precincts of Westminster Abbey, beneath whose “high embowed roof” repose the sacred ashes of the illustrious dead. 

Embowed′, arched, vaulted: bent like a bow: the heraldic term noting anything bent like a bow—as, e.g., the arm of a man.

But let my due feet never fail To walk the studious cloisters pale, And love the high embowed roof With antique pillars massy proof, etc.”

But let my due feet never fail To walk the studious cloisters pale, And love the high embowèd roof, With antique pillars, massy proof, And storied windows, richly dight, Casting a dim religious light.
