saying

[wowenglish1]

He left school and traveled to Europe, saying that he wanted to find himself.

I have two questions.
1. I wonder if "saying" is participle or anything.
2. I would like to know the subject of "say".

I think it's a participle and the subject is 'he'.
I might want to read this thread: https://www.usingenglish.com/forum/ask-teacher/115200-adverbial-participle.html

Right. Saying = present participle
