The anonymous author of „Newes from Graves-End“ 1603 (Shakespeare experts assume Thomas Dekker / Thomas Middleton) belongs to those frontmen and certainly was the poet genius alias Shakespeare (not to be confused with the Stratford man)...
In the dedicatory Epistle to himself --- he calls himself at the beginning Nicholas Nemo, alias Nobody - and at the end devotes the epistle " to None but thy [him] selfe, Some-body". This allegory is tightly contextually connected to John Davies' epigrams 159, 160, 161 in the Scourge of folly (1611?)
Epigramm 159: To our English Terence Mr. Will: Shake–speare.
Epigramm 160: To his most constant, though most vnknowne friend; No–body.
Epigramm 161: To my neere-deere wel-knowne friend; Some-body.
This inconceivable literary efficiency and productivity becomes visible in some lines of the epistle :
