The plate history of this item is complicated by its rarity; three states are assumed, but only two exemplars exist. It seems likely that the first state (if it exists) was published towards the end of the reign of Queen Anne (d. 1713). The second state (this exemplar) demonstrates clear evidence of re-engraving by a second engraver. Significantly, for dating purposes, these additions include ‘K. George Procl[aimed].’, recording the accession to the British throne of King George (I) on 1st August, 1714; George’s birthday is also inserted, although this is less obviously a later insertion.
A (presumed) third state exists at Kansas University. The Kansas copy bears the joint imprint of the partners Benjamin Scott and Charles Price inserted outside the lower border, and the cusps outside the ephemeris are filled with two panels of instructive text; ‘The description and use [of the Ephemerides] …’ and ‘Of the artificial lines of numbers sines and tangents. …’; a third cusp contains an advertisement for Scott and Price’s goods. However, their description makes no reference to the central parts of the engraving, in their words “wanting the moveable part consist[ing] of five circles”.
