citation of all legends which the author has placed on his map would
indeed fill many pages, and but few of these are here quoted.

In the southern hemisphere, and particularly conspicuous by reason of
the artistic cartouch in which it is placed, we find a reference to the
question of the proper location of the prime meridian,[40] somewhat
lengthy but quoted here in full. “Quamvis longitudinis initium
arbitrarium esset, ab occasu tamen ejus auspicium facere ideo veteribus
placuit quod illic aliquis terrae limen esset, qui ortum versus nullis
expeditionibus deprehendi potuisset. Atque eam ob causam Ptolemaeus
(cujus sedulitati et industriae Geographiae incolumitatem omnes, vel
inviti, debent) ab ultimo termino occidentis cognito, quae Insulae in
Atlantico Mari Fortunatae dictae sunt, auspicium fecit in eisque primum
Meridianum defixit: quod theticum principium deinceps fere omnes ejus
auctoritate moti retinuerunt. Interim hoc seculo nonnulli hoc principium
ex ipsa natura eruendum censuere. Qua in re acus Magneti junctae
indicium sequendum sibi sumpserunt, eumque primum Meridianum statuunt
quo in loco ea Boream spectat Quos plane allucinari addita illa Magneti
vis convincit, penes quem nullum longitudinis arbitrium sit, cum is ipse
sub eodem meridiano varium habeat enclisin prout huic aut illi
continenti vicinus fuerit. Sed et illi ipsi qui ita sentiunt, ob
instabile magnetis indicium, in primo Meridiano, multum inter se
dissentiunt. Quamobrem ut summo Geographiae commodo, certus aliquis
Meridianus tamquam primum principium servari et retineri possit,
Ptolemaei vestigiis insistentes, easdem Insulas, et iis Junonem, quae
Teneriffa vulgo creditur, delegimus, cujus excelsa illa et praerupta
petra, perpetuis nebulis obsessa, Indigenis El Pico dicta, primi
Meridiani terminus esto. Qua in re ab Arabum longitudinibus (qui extrema
Africae littora versus occidentem delegerunt), vix unius gradus
quadrante abimus diversi: quod quoque monuisse operae pretium putavi.”
“Although the beginning of longitude is arbitrarily selected
nevertheless it pleased the ancients to begin the counting of it from
the west, because there was the limit of the earth, as some thought,
while no expedition to the east was able to determine this. Therefore
Ptolemy, to whose application and industry all men, even though
unwilling to admit it, owe the preservation of geography (geographical
science), made the location (of the beginning of longitude) in the
farthest known limit of the west, which is called the Fortunate Islands,
in the Atlantic Ocean, and in them he fixed the first meridian. This
hypothetical beginning, almost all who came after him retained because
of his influence. But in our century there are some who have said that
