Petra in Aegypto
Petra in Aegypto (also spelled Petra in Ægypto) was a Hellenistic city and former bishopric in
Roman Egypt and remains a Latin Catholic titular see
.
History
Petra in Aegypto, identified with modern Hagar-En-Nauatiyeh, was important enough in the
Patriarchate of Alexandria
, but faded, presumably at the advent of Islam.
Little is known not even a single historically documented bishop, as it isn't mentioned in classical reference works like Lequien's Oriens Christianus.
Titular see
The diocese was nominally restored in 1933 as Latin
Titular bishopric
of Petra in Ægypto (Latin) / Petra di Egitto (Curiate Italian) / Petren(sis) in Æypto (Latin adjective).
It remains vacant, without a single incumbent. It is of the Episcopal (lowest) rank.
