That is very awkward, and many will want to edit it. Better to say "He was released from prison today." or, "He was set free today." "He was set free from prison today" might work, but the others are better.

Mark wanted to go, but not today.
As 'today' is the current time when the sentence is used, it does not make sense to say 'by today', as today has already been reached.A better way to phrase the sentence is 'Do you need it today.' This sentence makes sense, as it is possible for the action to be carried out at a later time on that day.

First off, there is technically no participial phrase in the sentence currently, for participial phrases must be set off by commas. If commas were included at the appropriate places to indicate a participial phrase, though, the sentence would read, "Simple jewelry, left behind by ancient Egyptians, can be very valuable today." The participial phrase in this case is "left behind by ancient Egyptians," because it modifies the subject (jewelry), is set off by commas, and is not a sentence in itself.
