These were originally personal names, frequently physical features. For example, the cognomen of Pūblius Ovidius Nāsō meant "nose". Before too long, cognomina were again inherited and ceased to be personal distinguishers. In the later centuries of the Empire, there was a proliferation of agnomina, a fourth name placed after the cognomen. Medieval Era and beyond Later with the gradual influence of Greek and Christian culture throughout the Empire, Christian religious names were sometimes put in front of traditional cognomina, but eventually people reverted to single names. By the time of the fall of the Western Roman Empire in the 5th century, family names were uncommon in the Eastern Roman Empire. In Western Europe, where Germanic culture dominated the aristocracy, family names were almost non-existent. They would not significantly reappear again in Eastern Roman society until the 10th century, apparently influenced by the familial affiliations of the Armenian military aristocracy. The practice of using family names spread through the Eastern Roman Empire and gradually into Western Europe, although it was not until the modern era that family names came to be explicitly inherited as they are today. Medieval Spain used a patronymic system. For example, Álvaro, a son of Rodrigo, would be named Álvaro Rodríguez. His son, Juan, would not be named Juan Rodríguez, but Juan Álvarez. Over time, many of these patronymics became family names, and they are some of the most common names in the Spanish-speaking world today. Other sources of surnames are personal appearance or habit, e.g. Delgado ("thin") and Moreno ("dark"); geographic location or ethnicity, e.g. Alemán ("German"); and occupations, e.g. Molinero ("miller"), Zapatero ("shoe-maker") and Guerrero ("warrior"), although occupational names are much more often found in a shortened form referring to the trade itself, e.g. Molina ("mill"), Guerra ("war"), or Zapata (archaic form of zapato, "shoe"). In England, the introduction of family names is generally attributed to the preparation of the Domesday Book in 1086, following the Norman conquest. Evidence indicates that surnames were first adopted among the feudal nobility and gentry, and slowly spread to other parts of society. Some of the early Norman nobility who arrived in England during the Norman conquest differentiated themselves by affixing 'de' (of) before the name of their village in France. This is what is known as a territorial surname, a consequence of feudal landownership. By the 14th century, most English and most Scottish people used surnames and in
