PHOTO ESSAY: The Samaritans on Passover 100 years ago. The Samaritans still sacrifice the Pascal Lamb (Lenny Ben DAvid, Arutz Sheva). There are lots of interesting photos of Samaritans c. 1899-1900 in the article, but you have to follow the American Colony link for photos of them celebrating Passover.
More on Samaritan Passover is here and links.
