Compare: Chisholm, Hugh, ed. (1911). "Schaffhausen (town)". Encyclopædia Britannica (11th ed.). Cambridge University Press. "[...] in 1050 we hear of the “ford” there across the Rhine. Hence it is probable that the name is really derived from scapha, a skid, as here goods coming from Constance were disembarked in consequence of the falls of the Rhine a little below."

"Some writers, however, prefer the derivation from Schaf (a sheep), as a ram (now a sheep) formed the ancient arms of the town, derived from those of its founders, the counts of Nellenburg."
