The lower part of the t.p. of the original being mutilated part of the imprint is lost ; conjecturally restored in part it reads: Impresso em ha cidade die Lixboa por hermao de Campos com gracia e priuilegio. The date of printing is probably between 1509 and 1518. In other imprints of this period the printer's name appears variously as Herman de Kempis, Kempos and Campos. cf. p. 8 9: also J. Bensaude, L'astronomie nautique au Portugal (Bern, 1912) p. 71, 168-170.
