Approaching Solar Eclipse. John Poulson.

Approaching Solar Eclipse.

Philadelphia: John Poulson, 1806. Narrow folio broadside, two deckle edges, woodcut and letterpress, 21” x 9.5” overall. / Two horizontal separations (one irregular) repaired resulting in disruption of several lines of text which are still legible, old adhesive stains in upper 6 inches, about very good. OCLC locates 5 extant copies. Item #100252

Rather rare broadside announcing the coming partial solar eclipse of 16 June, 1806 as predicted to be visible beginning at 9:42 in Philadelphia and ending at 12:35. A wonderful woodcut diagram illustrates the ecliptic arc and phases of the moons penumbra. Surrounding text provides an explanation extracted from “Darkness At Noon; or, The Great Solar Eclipse…” by an inhabitant of Boston (D. Carlisle & A. Newell, May 1806) describing the science behind this celestial event which was visible in totality this year at Boston. In addition to the pamphlet summation Poulson has included supplementary details relevant to the citizens of Philadelphia.

The size and format of this broadside suggest the survival rate was quite low explaining the apparent rarity.
