For a long time historians believed that the first wife of Kalman, king of Hungary (d 1116) was named "Busilla". She was a daughter of Roger I, most probably by his second wife, Eremburge of Mortain. This was from the error of a 14th-century Italian translator of an 11th-century chronicle, who misread the word "puella" and mistook this for the lady's name. The original account, by Geoffrey Malaterra, did not give her name. In 1963 Walter Holtzmann pointed out the problem and explained how it came about. In 1964 Holtzmann's explanation was accurately related for Hungarian readers by Elemér Mályusz. Neither of them suggested a name for the lady, contenting themselves with noting that she was not called "Buzilla". However, in 1968 Szabolcs de Vajay invented the name Felicia for her, with a false explanation that he repeated in 1972 - according to him (citing only Holtzmann, who had said nothing of the kind), her name was supposedly given in a Siciilian diploma written in Greek as "Eleutheria" (it wasn't). Vajay then asserted, wrongly, that the Latin form of Eleutheria was "Felicia" (eleutheria means freedom, not felicity that is usually 'eutuchia'), and that this was the lady's name. He sought to justify his bogus claim by analogy with Felicia of Roucy (the second wife of Sancho IV of Aragon), who he said was close to the Sicilian ruler's family (in fact she was a sister-in-law of one of the Hungarian queen's many first cousins). The alleged Greek diploma giving the lady's name as "Eleutheria" was actually a genealogy of the Hauteville family by the 17th-century Sicilian historian Rocco Pirri, and he gave the name as "Busilla or Elateria", not by any means the same as "Eleutheria". Pirri cited two 16th-century works, and as Holtzmann had noted the first of these gave no name while the second gave only "Busilla". So Vajay had managed to turn yet another repetition of the old mistake into a new one of his own imagination. Unfortunately his authority has been accepted without question by many historians, and the baseless "Felicia" is now taken into the historical canon as the anonymous queen's name. Peter Stewart
