Nevertheless, it is clear from the archaeology of numerous mithraea that most rituals were associated with feasting – as eating utensils and food residues are almost invariably found. These tend to include both animal bones and also very large quantities of fruit residues. The presence of large amounts of cherry-stones in particular would tend to confirm mid-summer (late June, early July) as a season especially associated with Mithraic festivities. The Virunum "album", in the form of an inscribed bronze plaque, records a Mithraic festival of commemoration as taking place on 26 June 184. Beck argues that religious celebrations on this date are indicative of special significance being given to the summer solstice; but this time of the year coincides with ancient recognition of the solar maximum at midsummer, whilst iconographically identical holidays such as Litha, St John's Eve, and Jāņi are observed also.
