Has antisemitism changed over time

actually yes

Explanation:

in the old ages the Jews basically ruled Jerusalem (hence the name) and people hated them for the way they treated the people there, not their religion. When Hitler came to power many years later after they had lost the rule of Jerusalem people started hating them for the way they horded money and their religion. Now people just hate them for their religion.

So yes antisemitism has changed over time.

the first forms of writing came from them in the form of pictographs around 3100 bc.

whats the question? im not quite understanding your question.
