The lighting colomne or sea-mirrour containing the sea-coasts of the northern, eastern and western navigation: setting forth in divers necessarie sea-cards all the ports, rivers, bayes, roads, depths and sands ...

As also the situation of the northernly countries, as islands, the strate Davids, the isle of Ian-Mayen, Bear-Island, Old-Greenland, Spitsbergen and Nova Zembla ... Gathered out of the experience and practice of divers pilots and lovers of the famous art of navigation. By Jan van Loon. Whereunto is added a brief instruction of the art of navigation, together vvith nevv tables of the suns declination, also an almanack extending untill the yeare 1661.

The third Example. Concerning those which are more Westerly with rising declination.

A certaine Ship comming upon the 9 of October in the third yeare after Leape-yeare upon the greate South Sea, neare the Coast of Peru, the Steerman desireth to know the Suns declination there at noone, hee findeth (out of a Globe or any other Table) that that Coast lyeth full 80 degrees more Westerly then Englands Lands End. The Sun must then run from the South over Englands end to the South of the foresaid Coast of Peru full 80 degrees, to which hee requireth about 5 houres and an halfe, so that when the Sun standeth there in the South, it is then from Englands end halfe an houre past 5 in the afternone. Hee findeth in these Tables the declination of that day 6 degrees 13 minutes by South the Line, and (out of that of the following day which is 6 degrees 36 minutes) that at that time in 24 houres the declination riseth 23 min.) therefore shall hee say: the declination riseth in 24 houres 33 minutes, how much then in 5 houres and a ½? facit full 5 minutes, and from thence wee find, that seeing the Sun running from the Meridian of Englands end to hert of the Coast of Peru riseth full 5 minutes, and thereupon the declination on that day is there 5 minutes more, even as the tables demonstrate. The declination then on that day on the Coast of Peru is 6 degrees 18 minutes.
