(TheTelegraph) - A study reveals that Richard III guzzled a bottle of wine a day during his last years – but he's far from the only ruler to have enjoyed a tipple.

The pressures of ruling a country must be difficult – so it’s perhaps no surprise that King Richard III turned to alcohol to drown his sorrows.

A study of the teeth and bones of Richard III towards the end of his life suggests that he drank around a bottle of wine a day.

The research, by the British Geological Survey and University of Leicester, revealed that the monarch described by Shakespeare as a "poisonous bunchback'd toad" enjoyed an extremely rich diet after ascending to the throne in 1483.

Analysis of samples taken from a femur, rib and tooth after his remains were found under a Leicester car park in 2012 showed that the monarch enjoyed a decadent menu including swans, heron, egret and freshwater fish such as pike, all washed down with up to three litres of alcohol a day.

"We know he was banqueting a lot more, there was a lot of wine indicated at those banquets and tying all that together with the bone chemistry it looks like this feasting had quite an impact on his body in the last few years of his life," Angela Lamb, a University of Leicester geochemist, told the BBC.

The team carried out of isotope analysis of the samples to measure the levels of certain chemicals, such as strontium, nitrogen, oxygen, carbon and lead, which can indicate the kind of foods a person ate.
