 Re: He is a writer fallen into oblivion
No - having + past participle as a subordinate clause doesn't usually replace a relative clause. It generally indicates one of the following :
a) a causal relationship between the past event and the proposition of the main clause :
Having already asked him several times, I didn't really want to do it again.
= As / Since I had already asked..... etc
b) a temporal reference - ie When/after
Having fried the onions, you then need to add the peppers.
= When you have fried ... (etc)
or with the meaning of If/Once. You could say eg :
Having fallen into oblivion, a writer will rarely re-emerge.
= If/once s/he has fallen into oblivion, a writer will rarely re-emerge.
Your sentence can't be interpreted as having any of these meanings, so no - the structure is not possible. |
