A pair from Tanis are attributed by Flinders Petrie to Pepi I.
The monuments discovered there, although only those in hard stone have survived, are more important than at any other site in the Delta except Tanis and cover a wider range, commencing with Khufu (Cheops) and continuing to the thirtieth dynasty.
Paid much attention to the Delta, which had been neglected until the days of Seti I., and resided there constantly; the temple of Tanis must have been greatly enlarged and adorned by him; a colossus of the king placed here was over 90 ft.
In historic times his cult was celebrated at Tanis Ind Ombos.
For this reason it is often hard to tell where the primitive cult-centre of a particular deity is to be sought; thus Horus seems equally at home both at Buto in the Delta and at Hieraconpolis in Upper Egypt,, and the earliest worship of Seth appears to have been claimed no less by Tanis in the north than by Ombos in the south.
On particular sites, Pyramids and Temples of Gizeh (1883); Tanis I.
In 1881 he began a long series of important surveys and excavations in Egypt, beginning with the pyramids at Giza, and following up his work there by excavations at the great temple at Tanis (1884), and discovering and exploring the long-lost Greek city of Naucratis in the Delta (1885), and the towns of Am and Daphnae (1886), where he found important remains of the time when they were inhabited by the Pharaohs.
The pyramid-fields of Memphis and Sakkara, and the necropolis of Meydum, and those of Abydos and Thebes were examined; the great temples of Dendera and Edfu were disinterred; important excavations were carried out at Karnak, Medinet-Habu and Deir el-Bahri; Tanis (the Zoan of the Bible) was partially explored in the Delta; and even Gebel Barkal in the Sudan.
The era of scientific excavation began with Flinders Petries work at Tanis in 1883.
A great temple at Tanis boasted a larger colossus than existed in Thebes: Heliopolis and Memphis must have been lavishly adorned, and the temples of Abu Simbel alone would have been sufficient to satisfy the ambition of many of the great Pharaohs.
