What I noticed first about the language in this television ad for the Prayer Cross (from Montebello Collections) — viewable here — was the reference to the cross as a “spiritual accessory”. Then I noticed a modifier in the ad:
When held up to the light, the entire Lord’s Prayer becomes instantly and almost miraculously visible.
That is, when the cross is held up to the light, the entire Lord’s Prayer etc. etc. The cross is mentioned in the previous context, of course, and it’s obviously topical in the context. So though the subjectless predicative adjunct would be labeled a “dangling modifier” by many people (because it doesn’t pick up the referent for the missing subject in the default way, from the subject of the main clause), it’s likely to escape most people’s notice (as it did mine for some time), because it’s so easily interpretable.
