[Rumil]

On the subject of the men of Esgaroth and Dale, JRRT's picture in the Hobbit shows the Lakemen wearing (rather exaggerated) 'Phrygian' caps.

I think these were associated with a number of Middle Eastern peoples, (including the Phrygians I guess) such as the Persians. Also they were worn by more 'northern' barbarian types such as the Dacians (who lived mostly in what is now Romania and for whom wearing a hat was considered a mark of nobility). These caps were later popular among the Anglo-Saxons.

I think in appearence the lakemen should be similar to Anglo-Saxon Fyrd, they are noted as using spearmen at the battle of the five armies. The Saxons were also known for their sailing skills.
