Nagnata

[1] It is located in northwest Hibernia between the mouths of the rivers Ravius (Ῥαουίος), perhaps the Erne, and Libnius (Λιβνίος), perhaps the Moy.

Surviving manuscripts of Ptolemy's Geography refers to the towns Hibernis (Teamhair'Erann/Tara), Rhaeba (Cruchain/Rathcroghan) and Magnata (Sligo) as "ἐπίσημος" (episēmos), an Ancient Greek word meaning "eminent" or "distinguished".

Evidence for earlier contact may be an Irish lunate spearhead from the 10th century BC which was found in the harbour of Huelva in southern Spain.

[full citation needed] Research by R. Darcy and William Flynn in 2008 at Oklahoma State University after correcting for various distortions in Ptolemy's co-ordinate system, identified Nagnata firmly in the vicinity of the modern Sligo town.

The place of assembly known to international traders would therefore seem to be most likely a coastal location somewhere between Ballisodare and Drumcliff, both ancient gathering points within a five-mile radius of the modern Sligo town.
