One of the Beasts is the Beast of Revelations from the Bible, this was noted from Fate/Prototype. The Seven Grand Classes likely mirror the original seven classes, Saber, Archer, Lancer, Rider, Caster, Berserker and Assassin.

Interesting thought on the Beasts though, Typhon and Fenrir seem likely.
