Despite the tormented national reality, the faith in the future redemption of Poland and the idea of change and purification gave birth in the works of the Polish romantics to the hope of salvation, of the advent of the divine kingdom on Earth. Undoubtedly an idea contributed to the birth of this optimistic vision, that was the conception of a Poland like the “Christ of the nations”, which took hold in the new mystical atmosphere of the early nineteenth century and which was combined with Christian eschatologism, revolutionary aspirations and hopes for the future redemption of history. The apocalyptic and millenarian motifs present in the Divine Comedy undeniably played a part in strengthening the messianic ideas of the romantics: the present from a fertile ground for evil and chaos, through suffering and destruction, became the privileged moment of expiation that prepared the advent of the city of God. The paper aims to analyze some motifs from Dante’s Paradise which inspired some of the most stunning pages of Polish romantic literature.

The author presents a sketch of the history of concepts and imaginative geography of the lands located in the hereafter: earthly and heavenly Paradise, Purgatory and Heaven. He reaches back to the origins of these images in ancient Eastern cultures, the culture of Antiquity, and patristic writings. He traces their development throughout the Middle Ages to the time of Dante, whose La Commedia sanctioned the separation of the hereafter into topographically located Hell, Purgatory and Paradise.

Recently, the rapid advancement of the IT industry has resulted in significant changes in audio-system configurations; particularly, the audio over internet protocol (AoIP) network-based audio-transmission technology has received favourable evaluations in this field. Applying the AoIP in a certain section of the multiple-cable zone is advantageous because the installation cost is lower than that for the existing systems, and the original sound is transmitted without any distortion. The existing AoIP-based technology, however, cannot control the audio-signal characteristics of every device and can only transmit multiple audio signals through a network. In this paper, the proposed Audio Network & Control Hierarchy Over peer-to-peer (Anchor) system enables all audio equipment to send and receive signals via a data network, and the receiving device can mix the signals of different IPs. Accordingly, it was possible to improve the system-application flexibility by simplifying the audio-system configuration. The research results confirmed that the received audio signals from different IPs were received, mixed, and output without errors. It is expected that Anchor will become a standard for audio-network protocols.
