paragraph_text: Numbering of popes
  
  Regnal numbers follow the usual convention for European monarchs. The first pope who chooses a unique name is not usually identified by an ordinal, John Paul I being the exception. Antipopes are treated as pretenders, and their numbers are reused by those considered to be legitimate popes. However, there are anomalies in the numbering of the popes. Several numbers were mistakenly increased in the Middle Ages because the records were misunderstood. Several antipopes were also kept in the sequence, either by mistake or because they were previously considered to be true popes.
