This uncommon chart of the entrance to the Rio de la Plata originally appeared on a sheet with three other charts. It depicts Buenos Aires and Santa Fe in miniature plan form and identifies several smaller rivers. Islands, soundings, banks, and anchorages fill the water. The chart includes a compass rose and scale of English leagues. It was published in Atlas Maritimus & Commercialis, an atlas with several joint publishers, among them James and John Knapton, William and John Innys, and John Senex. Senex is often credited with preparing the various charts therein. Most likely engraved by Samuel Parker, who is credited on other charts in the atlas. According to Shirley, the atlas is often catalogued under Astronomer-Royal Edmund Halley, who contributes an introductory note on the projection used throughout the atlas.
