File:Floral capital tops - Temple of Isis (14467449911).jpg

From Nectanebo's monument north, there are two colonnades, one on the east side and another on the west of an outer courtyard that leads to the first temple pylon. The western half of the colonnade is the more complete, and is pierced with windows originally looking toward the island of Biggeh. A nilometer descends the cliff from here. The colonnade is about one hundred yards long and contains thirty-one of the original thirty-two columns. The column capitals tops are floral, and remarkable in their variety with no two being alike. Most of the columns show carvings of Tiberius offering gifts to the gods. The ceiling, which is mostly destroyed, is decorated with stars and and flying vultures, while the rear wall has two rows of bas-reliefs of Tiberius and Agustus offering to the gods.

The eastern colonnade was never completed. On the south it abuts the temple of Arsenuphis, or Iry-hemes-nufer just to the north of the vestibule of Nectanebo. Arensnuphis was an obscure Nubian lion-god venerated as the companion of Isis. The temple was built by Ptolemy IV Philopator and extended by Ptolemy V Epiphanes. Here, the reliefs depict Ptolemy V before Isis and other gods, and also Ptolemy IV before Isis, Horus and Unnefer. The shrine was enclosed by walls that are ruined in some places but which have representations of Tiberius worshipping Osiris, Isis, Harsieses (Horus the Elder), Nephthys, Khnum, Satis, Anukis, Arsenuphis and Tefnut.

The eastern colonnade is partly roofed and has seventeen columns, only six of which have their capitals completed. Behind (to the north) of the Temple of Arsenuphis and to the east of the eastern colonnade is the ruined chapel of Mandulis, another Nubian deity. At the northern end of the colonnade is the Temple of Imhotep.
