Poor Robin : 1666. An almanack after a new fashion. Being the second after bissextile, or leap-year. Wherein the reader may see (if he be not blind) many remarkable things worthy of observation. Containing a two-fold kalender, viz. The Julian or English; and the Roundheads or fanaticks: with their several saints days, and observations upon every month. Written by Poor Robin, Knight of the Burnt Island, a well-willer to the mathematicks. Calculated for the meridian of Saffron-Walden, where the May-pole is elevated (with a garland on the top of it) two yards and a half above the market crosse.
