Samuel Primo (c. 1635 in Jerusalem – 1708 in Adrianople), was a prominent Sabbatean sectarian of the 17th century.
[1] Primo was one of the earliest followers of Sabbatai Zevi, the self-proclaimed Jewish messiah.
Primo became Zevi's private secretary on Zevi's journey from Jerusalem to Smyrna in 1665, cleverly managing to give to the advent of the pseudo-Messiah an air of dignity.
From Smyrna, Primo spread the news among foreign Jews that the Messiah had actually appeared.
After Zevi converted to Islam, Primo explained this apparent apostasy as having been foreordained in the Messianic role.
