Pseudo-Ptolemy
Pseudo-Ptolemy is a designation used for the authors of pseudepigrapha that appeared under the name of the astronomer and geographer Ptolemy. These are not authentic works of Ptolemy but were either forged in his name or were mistakenly taken to be his. Although Ptolemy wrote in Greek, Pseudo-Ptolemaic works are sometimes known only from translations or purported translations in Arabic and Latin. Many are of medieval origin.
