How do Pauli and Dirac Matrices Relate to Quaternions?

[Hymne]

Does anybody know a good thread, homepage or book that takes up different interpretations of Pauli and Dirac matrices with the connection to for example quaternions or bivectors?
Maybe someone could comment on this?

I strongly recommend Doran and Lasenby, Geometric Algebra for Physicists. If you read this book carefully, all will be clear!

A nicely written introduction on quaternions and the Dirac equation:
