If you went "huh?" when you read that title then you haven't thought about how "Oxyrhynchus" would translate into English.

The "What's New in Papyrology" blog pointed to mention of a book by this title awhile back. Today they pointed to a review of City of the Sharp-Nosed Fish: Greek Lives in Roman Egypt (amazon.com) in the New Statesman.

Do check out the review. The book sounds fantastic.
