2011, Michael Elazar, Honoré Fabri and the Concept of Impetus: A Bridge between Conceptual Frameworks (Boston Studies in the Philosophy of Science 288), Springer Science+Business Media, ISSN 00680346, →ISBN (13), →ISBN (e-ISBN), part III: Violent Motion, chapter xiv: “Motion in the Void”, § 14.1: ‘De loco and the Defense of Void’, page 137:
The beginning of De loco is dedicated to proving that beyond “Aristotelian place” (locus) – “the innermost motionless boundary of what contains” – there must exist a more general type of space, ubicatio, which allows for existing in a void, where of course there is nothing which could “contain”. We have encountered (in Section 9.1) Fabri’s notion of duratio – the “principle of existing in time”, an autonomous concept of time which does not depend on motion, an intrinsic ratio formalis “by which a certain thing is said to be now, before, after (nunc, ante, post)”. Likewise, ubicatio is defined by him as a “principle of existing in place”, a ratio formalis by which “something is in that place, in another place, in any place (ibi, alibi, alicubi)”. Later Fabri explains that ubicatio is a mode, and thus cannot exist – not even by a miracle – separated from the subject it modifies.

Quies poſitiua localis non eſt locus quí:nec vbicatio ſuꝑficialis.
1648, Honoré Fabri, Metaphysica demonstrativa; sive, Scientia rationum universalium, book 8, definition 1, page 313:
Ubicatio est ratio existendi in loco. Non dico esse aliquid distinctum ab eo, quod in loco est, vel ab ipso loco… ita prorsus concretum hoc locatum (ut ita dicam) ubicatum, esse in loco, esse hic, vel illic, esse loci, habet rationem formalem huius esse localis, quam voco ubicationem, qua scilicet res aliqua ibi, alibi, alicubi est.
ibidem, book 8, proposition 14, page 333:
Septimo, non potest ubicatio existere separata, quia est modus.
