Editing Fountain pen (section)

=== Early prototypes of reservoir pens ===

There is compelling evidence that the first working fountain pen was constructed and used during the [[Renaissance]] by artist and inventor [[Leonardo da Vinci]].  Leonardo's journals contain drawings with cross-sections of what appears to be a reservoir pen that works by both gravity and capillary action.  Historians also took note of the fact that the handwriting in the inventor's surviving journals is of a consistent contrast throughout, rather than the characteristic fading pattern typical of a quill pen caused by expending and re-dipping.  While no physical item survives, several working models were reconstructed in 2011 by artist Amerigo Bombara that have since been put on display in museums dedicated to Leonardo.<ref name="tusc_Lape">{{Cite web | title = La penna di Leonardo alla sala regia - Tusciaweb.eu | trans-title =  | author =  | work = Tusciaweb.eu | date = September 7, 2011 | accessdate = 2016-11-09 | url = http://www.tusciaweb.eu/2011/09/la-penna-di-leonardo-alla-sala-regia/ | language = it  | quote =  }}</ref>
