The column next to that date notes that there is village structure dated to the 9th century BC; the 753 date is actually downright mythical rather than archeological, but where some mythical dates exaggerate antiquity (e.g. lists of Sumerian kings) this mythical date cuts antiquity short to give city founding credit to the (probably entirely mythical?) Romulus rather than give recognition to the prior Greek settlement on the Palantine Hill (which Roman sources mentioned, while still claiming to be only as old as Romulus' city). It's an odd cultural carry over from Roman times to see in a wikipedia page, recognized in one column and ignored in the one prior.
much of rome's ancient history is "mythical" in that it the only historical evidence we have are the legends handed down from that time. many of them appear to be attempts to reconcile the status of the early republic with the foundational history of the village/town/location of rome.
i loved reading the rise of rome, by anthony everitt.
