Okay so here's an updated list:
Pseudepigrapha (including the Letter of Aristeas)
*Demetrius the Chronographer
*Aristobulus of Paneas
Philo of Alexandria
Flavius Josephus the Historian
Dead Sea Scrolls
(from my understanding the Talmud should contain all the teachings of the Mishna, i.e. Gemara, and all the commentaries of the Mishna, including teachings of Hillel and Shamai and their Rabbinic successors)
Targum Ps-Jonathan (Yerushalmi)
Siddur (although compiled late, yet of ancient importance)
(I know, I went a bit further than Nicea...considering that there are some complications in these writings and how they're compiled, I'm going up about about the 7th Century)
In addition to the above, there's the Midrashim:http://en.wikipedia.org/wiki/Midrashim
From what I can gather, the Midrash is a subset of Rabbinic literature (Rabbinic literature composed of Midrash and Tosefta) that are exegetical in nature. The Midrash is made up of Midrash Halakha (613 laws) and Midrash Aggadic (non-legal).
Midrash Halakha (Akiba vs. Ishmael):
--Mekhilta de-Rabbi Yishmael on Exodus
--Mekhilta de-Rabbi Shimon bar Yohai on Exodus
--Sifre on Numbers & Deuteronomy
--Sifre Zutta on Numbers
--Mekhilta on Deuteronomy
And as for the Midrash Aggadah...I shall consult the book posted.
Did I also get all the Hellenic authors/writings posted up there, or am I missing anything?
Another question: According to this timeline:http://www.myjewishlearning.com/texts/About_Jewish_Texts/Jewish_Texts/Timeline.shtml
There's something called "Discussion of Intention of Prayer". What is that? I'm having trouble identifying this as the title is a very vague title.
