Albert Pike's 33rd Degree Ritual

From the National Heritage Museum website:

Albert Pike (1809-1891), Sovereign Grand Commander of the Scottish Rite’s Southern Jurisdiction from 1859 to 1891, revised all of the Scottish Rite degree rituals, including the 33°, during his tenure. A handsomely bound book, containing Pike's reworked version of the 33°, was presented to the Supreme Council, Northern Masonic Jurisdiction (NMJ) in 1870. This manuscript version of Pike's 33° ritual is currently on view in the Van Gorden-Williams Library & Archives reading room exhibition, Secret Scripts: Masonic and Fraternal Ritual Books, at the Scottish Rite Masonic Museum & Library.

This ritual is from 1870 and was his 33rd degree ritual.
