Fascinating SC — though this seems to date to the Assyrian-nubian period (747 to 332 BC). Anubis is an older god — afaik he is dated to pre-dynastic Egypt (pre 3100 BC) — seems like his worship was continued far longer than other deities in the Egyptian pantheon
The Egyptians had a raft of different deities, which got edified, demoted, and/or merged over time, as Egypt went from being a collection of city-states to having several larger kingdoms, with occasional unification (a fact, despite the picture of unified nation-state that was the official line, even in antiquity). Aten, an Old Kingdom deity, was raised to supremacy by Akhetaten, for reasons which remain obscure (although the political motivation may be the only thing at work there). The Egyptians had a number of different cat deities, but eventually only one was supreme, the others dwindling into very local worship.
