Theological treatises stand apart in the corpus of Boethius' writings. They significantly differ in style from Boethius' other works, which tend to simplicity and clarity. The style of Boethian theological treatises that is known in the researches as the obscure style (stylus obscurus), is called the style of brevity (stylum brevitate) by Boethius himself. The article shows that the style of brevity acquired its name due to the syntactic compression it uses. The use of a stylistic device based on ellipsis is examined, namely, the copula drop. Syntactic compression is an instance of a general linguistic phenomenon of compression, which at the syntactic level leads to polysemy. Consequently, the stylistic devices used in the theological treatises aim at creating an artificial ambiguity, which opens a possibility of parallel reading. Copula drop emancipates the existence verb the most significant element, which begins to function as an autonym. Given the absence of heterogrammatical symbols or any other ways of marking autonyms in written speech, it becomes possible to consider the style of brevity an autonymic means of expression. Quomodo trinitas unus deus ac non tres dii is considered to be an attempt of a rational explanation of the thesis postulating the unity of the Trinity; however, the object of investigation is not a dogma, but a theological construct: the meaning of the connection in the dogma is logically inexpressible, and the elliptical construction is a syllogism, hence a copula is implied. The form that implicitly contains a copula allows Boethius to place the statement among identity sentences. From investigating the thesis of the Trinity Boethius proceeds to universal analysis and defines the type, to which theological statements belong in general. They are a modification of a metaphysical, namely ontological, statement. Theological statements as such statements about God need special reservations and specifications. Using the style of brevity, Boethius implicitly introduces the structural rules of construction of theological statement. These rules are placed at a meta-text level and are realized through parallel reading. The est element plays a special role. As a reduced copula, it takes part in creating a parallel text, and as an autonym, in constituting a philosophical meaning. At this level, philosophical substance receives not a metaphysical, but a semiotic form of expression, yet, due to meta-textual organization, it is perceived, if not consciously, then unconsciously. In the latter case, it influences the formation of discursive structures, which should have had an effect on the development of the philosophical thought of the later centuries.

Доказывается, что «стиль сокращений» получил свое название от применяемых в нем конструкций синтаксического сжатия. Рассматривается использование эллипсиса, а именно: пропуск глагола-связки. Пропуск связки высвобождает глагол бытия, который начинает функционировать как автоним; поэтому, в условиях отсутствия гетерограмматических символов или иных способов маркирования автонимов в письменной речи, становится возможным рассматривать «стиль сокращений» как автонимичный способ выражения.
