BTW, beware of dates of WQS, they were converted from Julian to Gregorian. Property talk:P571If you use just "wdt" it accesses a triple that doesn't include the date precision. Try the "before year 1" query on Thank you! I solved the problem in this way:

Use at

PREFIX wikibase: <http://wikiba.se/ontology#>
PREFIX wdt: <http://www.wikidata.org/prop/direct/>
PREFIX wd: <http://www.wikidata.org/entity/>
PREFIX bd: <http://www.bigdata.com/rdf#>
SELECT ?item ?itemLabel ?genreLabel (CONCAT(str(1+YEAR(?date)*-1), "BC") as ?yearBC) ?title
WHERE {
  ?item wdt:P50 wd:Q43353 .
  ?item wdt:P136 ?genre .
  ?item wdt:P571 ?date .
  ?item wdt:P1476 ?title .
    SERVICE wikibase:label { bd:serviceParam wikibase:language "it,grc" }    
} ORDER BY ?date
