Cruciniacus) and Frederick I, Holy Roman Emperor (in 1179 as Cruczennach). On the other hand, the Crucinaha in Emperor Otto III's documents from 1000 (which granted the rights to hold a yearly market and to strike coins) is today thought to refer to Christnach, an outlying centre of Waldbillig, a town nowadays in Luxembourg. In mediaeval and early modern Latin sources, Kreuznach is named not only as Crucenacum, Crucin[i]acum (adjective Crucenacensis, Crucin[i]acensis) and the like, but also as Stauronesus, Stauronesum (adjective Staurone[n]s[i]us; from σταυρός "cross" and νῆσος "island") or Naviculacrucis (from navicula, a kind of small boat used on inland waterways, called a Nachen in German, and crux "cross"). Sometimes also encountered is the abbreviation Xnach (often with a Fraktur X, with a cross-stroke: ). About 1017, Henry II, Holy Roman Emperor enfeoffed his wife Cunigunde's grandnephew, Count Eberhard V of Nellenburg, with the noble estate of Kreuznach and the Villa Schwabenheim belonging thereto. After his death, King Henry IV supposedly donated the settlement of Kreuznach to the High Foundation of Speyer in 1065, who then transferred it shortly after 1105 – presumably as a fief – to the Counts of Sponheim. On Epiphany 1147, it is said that Bernard of Clairvaux performed a miraculous healing at Saint Kilian's Church. In 1183, half of the old Frankish village of Kreuznach at the former Roman castrum – the Osterburg – burnt down. Afterwards, of the 21 families there, 11 moved to what is now the Old Town (Altstadt). In the years 1206 to 1230, Counts Gottfried III of Sponheim (d. 1218) and Johann I of Sponheim (d. 1266) had the castle Kauzenburg built, even though King Philip of Swabia had forbidden them to do so. Along with the building of this castle came the rise of the New Town (Neustadt) on the Nahe's north bank. In the years 1235 and 1270, Kreuznach was granted town rights, market rights, taxation rights and tolling rights under the rule of the comital House of Sponheim, which were acknowledged once again in 1290 by King Rudolf I of Habsburg. In 1279, in the Battle of Sprendlingen, the legend of Michel Mort arose. He is a local legendary hero, a butcher from Kreuznach who fought on the Sponheim side in the battle against the troops of the Archbishop of Mainz. When Count Johann I of Sponheim found himself in difficulties, Michel Mort drew the enemy's lances
