In this article, we address the issue of poetic translation and re-translation, beginning from a theoretical approach and, then, contextualizing it by the Italian versions of Antonio Machado’s poetry during the 20th century and the last decades. In the first part, we underline the most important elements that make poetic (re-)translation an autonomous, creative and original “literary genre”. In the second part, we compare Machado’s translations by Oreste Macrì to the ones newly realized by the author of the present article in terms of language, strategies and editorial target.

The article deals with the semantic development of Proto‑Slavic * lichъ. This adjective has many disparate meanings in Slavonic languages which have predominantly developed from the Proto‑Slavic meaning ‘odd, uneven’. The concept of ‘oddness, unevenness’ was mostly viewed as something undesirable and harmful which is reflected by meanings like ‘needless, futile, vain, wretched, evil, ominous etc.’. There is, however, also a group of positive meanings in Slavic languages, such as ‘free, daring, high‑spirited, skilful, famous’. The semantic shift to these meanings has not been satisfactorily explained. We suggest a development via the meanings ‘free from sth, singular’ (partially attested in Old Church Slavonic and some other Slavic languages) as one of the possible directions of semantic development of * lichъ from which the aforementioned positive meanings could be explained.

The problem of the optimal driving technique during the fuel economy competition is reconsidered. The vehicle is regarded as a particle moving on a trace with a variable slope angle. The fuel consumption is minimized as the vehicle covers the given distance in a given time. It is assumed that the run consists of two recurrent phases: acceleration with a full available engine power and coasting down with the engine turned off. The most fuel-efficient technique for shifting gears during acceleration is found. The decision variables are: the vehicle velocities at which the gears should be shifted, on the one hand, and the vehicle velocities when the engine should be turned on and off, on the other hand. For the data of students’ vehicle representing the Faculty of Power and Aeronautical Engineering it has been found that such driving strategy is more effective in comparison with a constant speed strategy with the engine partly throttled, as well as a strategy resulting from optimal control theory when the engine is still active.

The article is a topic outline of the theology of the Church’s unity. It shows the spectrum of contemporary reflection on this attribute of the Church mentioned in the Nicene-Con-stantinople Symbol (credo in unam Ecclesiam). The reflection includes biblical categories, especially the idea of koinōnia/communio, emphasizing the Trinitarian basis for unity of the Church, and its concrete means – bonds of unity. Among these means of unity, particular attention is paid to the bond of faith, the sacraments and ecclesiastical governance, nota-bly the universal ministry of Christian unity. Individual Churches (denominations) have different visions of unity, but also these concepts are the subject of ecumenical dialogue. The most recent ecumenical vision on the Church, including its unity, is the document of the World Council of Churches Commission on Faith and Order, Towards a Common Vision of the Church (published in 2013). Christian Churches involved in the contemporary ecumenical dialogue are aware that the unity of the Church is a reality given and set, yet incomplete and imperfect, so to speak “on the way”. In this sense they can express their spero in unam Ecclesiam.
