   Note: Have, as an auxiliary verb, is used with the past
         participle to form preterit tenses; as, I have loved; I
         shall have eaten. Originally it was used only with the
         participle of transitive verbs, and denoted the
         possession of the object in the state indicated by the
         participle; as, I have conquered him, I have or hold
         him in a conquered state; but it has long since lost
         this independent significance, and is used with the
         participles both of transitive and intransitive verbs
         as a device for expressing past time. Had is used,
         especially in poetry, for would have or should have.
         [1913 Webster]

               Myself for such a face had boldly died.
