I have a photocopy of William Molyneux' "Sciothericum Telescopium" Dublin 1686, and can confirm that he uses the term "Equation of Time". The title of Chapter X is "Concerning the Astronomical Equation of Time and the Tables thereof":
"Being now upon the business of Time, and the accurate observation thereof, so as thereby to regulate curious Time-keepers; it will not be improper to our subject to speak something of the Inequality of natural Days; a matter that has exercised the thoughts of all Astronomers in all ages: And though all have allowed that there really is such an Inequality, yet they have much disagreed in assigning its quantity, or demonstrating the reason and affections thereof; till at last our most Learned and Ingenious English Astronomer, and my Honoured Friend Mr. John Flamsteed Math. Regius, has determined the Controversy and by most evident demonstrations has put the matter beyond further dispute, clearly evincing both the Reasons, Affections, and Quantity of this Inequality. His Dissertation concerning this is annex'd and publish'd at the end of the Opera Posthuma Jeremiae Horroxcii, Lond. 1673.4to. From which (with my esteemed Friend's leave) I shall present the Reader with the following Schemes and Demonstrations."... ************************** (Dr) Charles Mollan 17 Pine Lawn Newtownpark Avenue Blackrock Co.
