May: Maia, Roman goddess, mother of Mercury by Jupiter and daughter of Atlas,

June: Juno, chief Roman goddess,

July: Renamed for Julius Caesar in 44 BC, who was born this month; Quintilis, Latin for fifth month, was the former name (the Roman year began in March rather than January),

August: Formerly Sextilis (sixth month in the Roman calendar); re-named in 8 BC for Augustus Caesar,
