Who does he meet first in the woods?

Goodman Brown leaves his house in Salem Village at sunset. His wife, Faith, is not very happy with the idea that he has business to attend to in the night. She begs her husband to postpone his business until sunrise, but he is determined to complete it in the night. She watches him as he walks away until he reaches the corner of the meeting house.
Goodman walks into the forest. He chooses a “dreary path” that is quite dark, so he is filled with fear as he thinks of what might be hidden in the shadows of the trees. Beyond a “crook on the path” he sees a man. The man is dressed in “grave and decent” clothes and is seated beneath an old tree. The man is about fifty years of age and closely resembles Goodman. He carries a staff that looks like a “big black snake”—this is the only remarkable thing about him. Also, it can be seen that, though appearing simple in manner and appearance, the old man is highly knowledgeable in matters of the world. The man has been waiting for Goodman. The two seem to have planned to meet in the forest. They intend to travel together to a certain place deep in the forest. When Goodman approaches him, he says “you are late Goodman Brown. The clock of the old South was striking, as I came through Boston; and that is full fifteen minutes agone.”
The mysterious man with the serpent staff is, thus, the first person that Goodman meets in the forest. Later on, the reader realizes that the strange man is actually the devil.
