Avodah Zarah 51 - Accoutrement of an Idol
If, on top of Markulis, one found coins, a garment, or utensils, they are permitted, as long as they are placed in such a manner that they cannot be considered adornments. Real adornments would be prohibited, unless nullified by an idolater. However, if he found vines bearing clusters of grapes, wreaths of grain, or glass jars with wines, oils, and fine flours - or anything the likes of which was brought on the Temple Altar - it is prohibited to use, because they are presumed to be offerings to the idol.
