Isidore of Seville [7th century CE] (Etymologies, Book 12, 6:38): The Syrian city now called Tyre was once called ‘Sarra’ after a certain fish that is abundant there, which they call sar in their language. From this name was drawn the name of small fish similar to these called sardae and ‘sardines’ (sardina). - [Barney, Lewis, et. al. translation]
