He bade them remember the tune, and promised them that whenever they heard it they might be sure their king was very near.
[Sidenote: Embassy to Constantinople.] Arrived at Constantinople, the ambassadors made known their errand, but were immediately cast into prison, in spite of the empress's intercession in their behalf.

Here the noblemen languished month after month, in a foul dungeon, while Rother impatiently watched for their return.

When a whole year had elapsed without his having heard any tidings, he finally resolved to go in disguise to Constantinople, to ascertain the fate of his men and win the lovely princess Oda for his bride.
Berchther, hearing this decision, vowed that he would accompany him; but although all the noblemen were anxious to escort their beloved king, he took only a few of them with him, among whom was Asprian (Osborn), king of the northern giants, with eleven of his tallest men.
[Sidenote: Rother and Constantine.] Rother embarked with this little train, and sailed for Constantinople over the summer seas; and as he sat on deck, playing on his harp, the mermaids rose from the deep to sport around his ship.

According to a prearranged plan, Rother presented himself before Constantine as a fugitive and outlaw, complaining bitterly of the King of the Lombards, who, he declared, had banished him and his companions.
Pleased with the appearance of the strangers, Constantine gladly accepted their proffered services, and invited them to a banquet, in the course of which he facetiously described how he had received Rother's ambassadors, who were still languishing in his dampest dungeons.

This boastful talk gradually roused the anger of the giant Asprian, who was but little accustomed to hide his feelings; and when the emperor's pet lioness came into the hall and playfully snatched a choice morsel out of his hand, he impetuously sprang to his feet, caught her in his powerful grasp, and hurled her against the wall, thus slaying her with a single blow.
[Illustration: ASPRIAN SLAYING THE LION .-- Keller.] Constantine was somewhat dismayed when he saw the strength, and especially the violence, of the new servants he had secured; but he wisely took no notice of the affair, and, when the banquet was ended, dismissed Rother and his followers to the apartments assigned them.
