Nathaniel Ponder at the Peacock in the Poultrey

Nathaniel Ponder at the Peacock in the Poultrey, was publisher of the first edition of The Pilgrim's Progress by John Bunyan.

"Nathaniel Ponder" - John Bunyan had an affinity for Nathaniel Ponder. Not only was Nathaniel a publisher of nonconformist literature, but he had spent time in prison for it, much the same as John Bunyan, only for a far shorter time period.

At the "sign of the Peacock" - An  identification sign (signboard) outside the business. Graphical signs were used because much of the population was illiterate.

"In the Poultry" - Poultry is a road in central London. The roads go from major intersection to major intersection only, so it was a short stretch of road (Poultry is between Cheapside and Cornhil). At some point the poultry trade was at that location.

"Near Cornhil" - Cornhil was the same road as Poultry only further down, indicating the business was down near where Cornhil started.
