Pompeiis
Pompeiis is a term that appears in discussions of Latin language and Roman names rather than as a distinct historical place or entity. In classical Latin, the proper name Pompeius (Pompey the Great) is most often declined in forms such as Pompeii (genitive singular) and Pompeis (dative or ablative plural). The spelling Pompeiis is not part of the standard classical declension pattern and is encountered only in specific manuscripts, regional spellings, or modern reconstructions. When encountered, it should be interpreted from its surrounding grammatical context rather than taken as a standalone name.
The best-known bearer of the name is Pompeius Magnus, commonly known in English as Pompey the Great,
Pompeiis should not be confused with Pompeii, the ancient city near Naples famous for its well-preserved ruins
