Etymology of Vistula name
The name was first recorded by Pomponius Mela in a.d. 40 and by Pliny in a.d. 77 in his Natural History. Mela names the river Vistula (3.33), Pliny uses Vistla (4.81, 4.97, 4.100). The root of the name Vistula is Indo-European *u?eis- ?to ooze, flow slowly? (cf. Sanskrit ?????? / ave?an ?they flowed?, Old Norse veisa ?slime?) and is found in many European rivernames (e.g. Weser, Viesinta).2 The diminutive endings -ila, -ula, were used in many Indo-European languages, including Latin (see Ursula).
In writing about the Vistula River and its peoples, Ptolemy uses the Greek spelling Ouistoula. Other ancient sources spell it Istula. Ammianus Marcellinus refers to the Bisula (Book 22), note the lack the -t-. Jordanes (Getica 5 & 17) uses Viscla while the Anglo-Saxon poem Widsith refers to it as the Wistla.3 12th-century Polish chronicler Wincenty Kadłubek Latinised the rivername as Vandalus, a form presumably influenced by Lithuanian vandu? ?water?, while Jan Długosz in his Annales seu cronicae incliti regni Poloniae called the Vistula ?white waters? (Alba aqua), perhaps referring to the White Little Vistula (Biała Wisełka): ?a nationibus orientalibus Polonis vicinis, ob aquae candorem Alba aqua ... nominatur.?
