Where the terminology is intelligible the protases make astronomical sense.
Assyriologists have considered the omen texts a form of science in Mesopotamia primarily because many of the phenomena of interest in these texts are of the physical, natural, world.(4) Thus many of the omen protases of the celestial omen series Enuma Anu Enlil, parts of Summa alu dealing with fauna, of Summa izbu focusing on anomalous animal and human births, of Alamdimmu, that deal with the variable forms of the human anatomy, and even parts of the Ziqiqu dreambook, have come to be inspected as sources for understanding the Mesopotamian attempt to grasp the workings of nature.
The author explicitly limits himself to a text edition and does not try to comment on the astronomical phenomena occurring in the protases of the omens.
Fourth, Sandowicz demonstrates that, in these periods (earlier periods in Mesopotamia varied in this regard), negative promissory oaths and all assertory oaths consisted of the protases (e.g., "if I stole the sheep") of conditional statements with the apodoses (e.g., "may the gods punish me") going unstated.
Regarding the modal means used in conditional protases, in Old English, the verb may occur both in the subjunctive and in the indicative (Visser 1966: [section] 880), with the latter being the more common mood (cf.
This is, for example, the case with futures, purpose clauses, protases of reality conditions, temporal clauses introduced by conjunctions such as "until", and complements of verbs such as "be necessary".
For example, it has been argued (Sweetser 1990; Dancygier 1998; Dancygier and Sweetser 2005) that all conditional protases are causally related to their apodoses (so that when the content of the protasis becomes a fact or is accepted as true, the apodosis indicates the result in the content domain, the conclusion in the epistemic domain, or the speech act performed).
This correlation, though somewhat less perfect, is also often found with the negative element used in constituent negation, in whether TP or not constructions, in negative stripping, (3) and in negative elliptical protases of conditionals (the latter two illustrated here):
Each eventuality was the object of a separate rubric, and all were exhibited in the same grammatical form, repeated ad nauseam, as so many hypotheses, or 'protases', each followed by their results, or 'apodoses'." (49)
Irrealis in both the protases is marked by the inflexional subjunefive, as in Present-day English (Anderson 1991).
