Archaeologists have just uncovered proof that some of us have found doodles of doodles humorous for a very, very long time.
A giant ancient stone with a rude engraving has been unearthed by bemused archaeologists.
The team behind the discovery was shocked to find the ancient phallus engraved on a millstone while doing roadworks on the A14 in Cambridgeshire, England.
Not only is finding decorated millstones extremely rare, archaeologists were even more amused at finding the genital symbol, The Sun reports.
Only four decorated Roman millstones have been discovered from around a total of 20,000 in the UK.
Steve Sherlock, Highways England’s archaeology lead, said: “The phallus was seen as an important image of strength and virility in the Roman world.”
Mr Sherlock added that Roman fighters would often wear good-luck charms engraved with genitalia before entering battle.
It is the latest in a string of baffling discoveries dating back to Neolithic, Bronze and Iron Ages to Roman, Anglo-Saxon and medieval periods by archaeologists working on the £1.5 billion ($A2.7 billion) road upgrade project.
They have also found the earliest evidence of beer brewing in Britain – dating back to as early as 400BC.
Also discovered was only the second gold coin to be found in the country depicting Roman emperor Laelianus, who reigned for about two months in 269AD before he was killed.
