The Codex Leicester (also briefly known as Codex Hammer) is a collection of largely scientific writings by Leonardo da Vinci. The codex is named after Thomas Coke, later created Earl of Leicester, who purchased it in 1717. Of Leonardo's 30 scientific journals, the Codex may be the most famous of all.

The Codex provides an insight into the inquiring mind of the definitive Renaissance artist, scientist and thinker as well as an exceptional illustration of the link between art and science and the creativity of the scientific process.

The manuscript does not take the form of a single linear script, but is rather a mixture of Leonardo's observations and theories on astronomy; the properties of water, rocks, and fossils; air, and celestial light. The topics addressed include:

Physically, the Codex takes the form of 18 sheets of paper, each folded in half and written on both sides, forming the complete 72-page document. At one time the sheets were bound together, but they are now displayed separately. It was handwritten in Italian by Leonardo, using his characteristic mirror writing, and supported by copious drawings and diagrams.

Leonardo di ser Piero da Vinci (Italian pronunciation: [leoˈnardo da ˈvintʃi]  pronunciation (help·info); April 15, 1452 – May 2, 1519, Old Style) was an Italian Renaissance polymath: painter, sculptor, architect, musician, scientist, mathematician, engineer, inventor, anatomist, geologist, cartographer, botanist, and writer whose genius, perhaps more than that of any other figure, epitomized the Renaissance humanist ideal. Leonardo has often been described as the archetype of the Renaissance Man, a man of "unquenchable curiosity" and "feverishly inventive imagination". He is widely considered to be one of the greatest painters of all time and perhaps the most diversely talented person ever to have lived. According to art historian Helen Gardner, the scope and depth of his interests were without precedent and "his mind and personality seem to us superhuman, the man himself mysterious and remote". Marco Rosci points out, however, that while there is much speculation about Leonardo, his vision of the world is essentially logical rather than mysterious, and that the empirical methods he employed were unusual for his time.

Codex Leicester are a four piece band from Leicester (England). They comprise Dave Fellows (Guitar) Kris Tearse (Drums/Vocals) Tiernan Welch (Bass) and Scott West (Guitar/Vocals).

Conceived in 2010 by Scott West and Kris Tearse following the demise of post-grunge band Death of London, the song writing partnership grew quickly and productively. Dave Fellows, formerly of Pacific Ocean Fire and motion film soundtrack composing partner of Tearse joined shortly after before Tiernan Welch of defunct Public Relations Exercise joined later that year.

After a short period of gigging and 'viral propaghanda' created by design firm wetheconspirators the band quickly received praise and response from left-field specialist radio luminaries featuring on BBC Introducing as well as John Kennedy XFM, Adam Walton BBC Radio Wales and BBC Radio 1. A single Hey Hey Hot Legs was released through Big Scary Monsters records in 2011 and Function records, home of Maybeshewill amongst others are due to release their debut EP entitled Mad Man's Lullaby in April 2012 and features single Strong like Bull. The music video for the single was shot, edited and produced by 'wetheconspitators'.

Leicester (/lɛstər/ LESS-tər  pronunciation (help·info)) is a city and unitary authority in the East Midlands of England, and the county town of Leicestershire. The city lies on the River Soar and at the edge of the National Forest. In 2010, the population of the Leicester unitary authority was estimated at 306,600, the second highest in the region, whilst 441,213 people lived in the wider Leicester Urban Area in 2006, making Leicester the tenth most populous settlement in the United Kingdom and the UK's fourteenth largest urban area. It is the largest city in the East Midlands yet has the second largest urban area in the region behind Nottingham Urban Area. Eurostat's Larger Urban Zone listed the population of the area at 772,400 people as of 2004.

Ancient Roman pavements and baths remain in Leicester from its early settlement as Ratae Corieltauvorum, a Roman military outpost in a region inhabited by the Celtic Corieltauvi tribe. Following the demise of Roman society the early medieval Ratae Corieltauvorum is shrouded in obscurity, but when the settlement was captured by the Danes it became one of five fortified towns important to the Danelaw. The name "Leicester" is thought to derive from the words castra of the "Ligore", meaning camp of the dwellers on the (river) Legro. Leicester appears in the Domesday Book as "Ledecestre". Leicester continued to grow throughout the Early Modern period as a market town, although it was the Industrial Revolution that facilitated a process of rapid unplanned urbanisation in the area.
