At p. 195 of the December 1904 issue of “Terrestrial Magnetism” is a
short article relative to the claim made that the compass was invented
by a Veronese named Salomone Ireneo Pacifico (A.D. 776–846) during the
first half of the ninth century. It states that Bertelli considers this
due to a misinterpretation of an inscription on Pacifico’s tomb, and
it alludes to Bertelli’s previous paper on the subject in “Terrestr.
Magn.,” Vol. VIII. No. 4, p. 179 (see also the number of “Terrestr.
Magn.” for June 1905, p. 108, and the “Geographical Journal” for March
1905, pp. 334–335).
The earliest recorded use of the compass in a Spanish vessel, according
to Capmany (“Memorias Historicas,” 1792), is to be found in the
Chronicle of Don Pedro Niño, Conde de Buelna, as follows: “It is
reported that Conde’s galleys left the island of La Alharina along the
coast of Bombay ... and the pilots compared their needles which had
been rubbed with the magnet stone....”
In Dr. Plumptre’s notes on Dante, reference is made to the fact that
the European knowledge of the magnetic needle came from Arabia, and,
like Humboldt, he quotes in support thereof an allusion from the
Spanish “Leyes de las Partidas” belonging to the first half of the
thirteenth century. The passage in the last named is spoken of by M.
Fern de Navarrete in his “Discurso historico,” etc., 1802 (II. tit. ix.
ley 28) and reads thus: “The needle which guides the seaman in the dark
night and shows him, both in good and in bad weather, how to direct his
course is the mediatrix (_medianera_) between the loadstone (_la
piedra_) and the north star....” Humboldt adds: “See the passage in
‘Las siete Partidas del sabio Rey Don Alonso el IX’ [according to the
usually adopted chronological order, Alfonso the tenth], Madrid, 1829,
Vol. I. p. 473.”[22]
On the other hand, the knowledge of the compass by the Arabs in the
thirteenth century has been most decidedly contested by E. Renaudot
(“Anciennes Relations des Indes et de la Chine,” Paris, 1717, p. 3);
by D. A. Azuni (“Dissertation sur l’origine de la Boussole,” Paris,
1809, pp. 102, 127); by Giovanni Battista Ramusio (“Coll. Voy.,” 1554,
Vol. I. p. 379); by A. Collina (“Considerazioni,” etc., Faenza, 1748,
p. 121, etc.). Buffon says (“Théorie de la Terre,” Paris, An. VIII.
tome i. p. 300): “I know that some pretend the Arabs have invented
the compass and have used it long before the French (see ‘Abrégé de
l’histoire des Sarrazins,’ de Bergeron, p. 119) ... but that opinion
always appeared to me devoid of reason; for there is no word in the
Arabian, Turkish or Persian tongue which can be made to signify the
compass.... They employ the Italian word _bossola_....”
