therefore loosing from troas, we came with a straight course to samothracia, and the next day to neapolis;
mi nerkeb di lbabuṛ si temdint n truwas, nṛuḥ qbala ɣer tegzirt n samutras. azekka-nni nkemmel ɣer temdint n nabulis.

and it came to pass, that after we were gotten from them, and had launched, we came with a straight course unto coos, and the day following unto rhodes, and from thence unto patara:
mi nemfaṛaq yid-sen, nerkeb lbabuṛ nṛuḥ qbala ɣer temdint n kus, azekka-nni ɣer temdint n ṛudus ; syenna nkemmel abrid ɣer temdint n batara.
