Olinthus bowed assent. He passed through the streets with a hasty step, but a quick and observant eye. Every now and then he exchanged a significant glance, a slight sign, with some passenger, whose garb usually betokened the wearer to belong to the humbler classes; for Christianity was in this the type of all other and less mighty revolutions--the grain of mustard-seed was in the heart of the lowly. Amidst the huts of poverty and labor, the vast stream which afterwards poured its broad waters beside the cities and palaces of earth took its neglected source. Chapter II THE NOONDAY EXCURSION ON THE CAMPANIAN SEAS. 'BUT tell me, Glaucus,' said Ione, as they glided down the rippling Sarnus in their boat of pleasure, 'how camest thou with Apaecides to my rescue from that bad man?' 'Ask Nydia yonder,' answered the Athenian, pointing to the blind girl, who sat at a little distance from them, leaning pensively over her lyre; 'she must have thy thanks, not we. It seems that she came to my house, and, finding me from home, sought thy brother in his temple; he accompanied her to Arbaces; on their way they encountered me, with a company of friends, whom thy kind letter had given me a spirit cheerful enough to join. Nydia's quick ear detected my voice--a few words sufficed to make me the companion of Apaecides; I told not my associates why I left them--could I trust thy name to their light tongues and gossiping opinion?--Nydia led us to the garden gate, by which we afterwards bore thee--we entered, and were about to plunge into the mysteries of that evil house, when we heard thy cry in another direction. Thou knowest the rest.' Ione blushed deeply. She then raised her eyes to those of Glaucus, and he felt all the thanks she could not utter. 'Come hither, my Nydia,' said she, tenderly, to the Thessalian. 'Did I not tell thee that thou shouldst be my sister and friend? Hast thou not already been more?--my guardian, my preserver!' 'It is nothing,' answered Nydia coldly, and without stirring. 'Ah! I forgot,' continued Ione, 'I should come to thee'; and she moved along the benches till she reached the place where Nydia sat, and flinging her arms caressingly round her, covered her cheeks with kisses. Nydia was that morning paler than her wont, and her countenance grew even more wan and colorless as she submitted to the embrace of the beautiful Neapolitan. 'But how camest thou, Nydia,' whispered Ione, 'to surmise so faithfully the danger I was exposed to? Didst thou know aught of the Egyptian?' 'Yes, I knew of his vices.' 'And how?' 'Noble Ione, I have been a slave to the vicious--those whom I served were his minions.' 'And thou hast entered his house since thou knewest so well that private entrance?' 'I have played on my lyre to Arbaces,' answered the Thessalian, with embarrassment. 'And thou hast escaped the contagion from which thou hast saved Ione?' returned the Neapolitan, in a voice too low for the ear of Glaucus.
