Velas: além do arrumando a mesa.

Além do uso decorativo, na arrumação de mesas, que não é o meu forte, existem alguns aspectos que podem ser acrescentados à funcionalidade das velas apresentada pela Chris, no seu post de hoje. Esta fonte de luz não tem uma idade definida, mas é bem velhinha (trocadilho besta). Existem descrições do seu uso, pelos egípcios, em período anterior a 3.000 A.C.
A iluminação sempre foi a sua função primordial.

O princípio de funcionamento das velas é extremamente simples. Transcrevo a explicação apresentada na wikipedia que traduz, muito bem, esta simplicidade – “durante a preparação da vela, previamente à ignição, o rastilho é saturado com o combustível na forma sólida. O calor do fósforo ou outra fonte de fogo irá derreter e vaporizar uma pequena porção de combustível que, no estado gasoso irá combinar-se com o oxigénio da atmosfera para formar a chama. A chama irá então providenciar calor suficiente para manter a vela acesa, numa típica reacção em cadeia auto-sustentável: o calor da chama derrete a superfície do combustível sólido, liquefazendo-o e fazendo-o deslocar-se em direcção ao rastilho e subi-lo, por capilaridade; o líquido passará, com o calor, para o estado gasoso, que irá ser consumido pela chama”.

Nada como a clareza e a descomplicação para aumentar o interesse dos leitores. Por favor não fechem o post! A partir de agora vou utilizar termos e descrições próprias. O que, por si só, pode comprometer mais ainda o interesse. De mais a mais vamos falar agora das utilidades, que não a iluminação, das velas.

No aspecto religioso as velas simbolisam a luz de Deus iluminando o caminho da fé e da verdade. Nas cerimônias fúnebres compõe o ambiente e a sua chama serve de guia para o caminho do céu. Em ocasiões menos formais, as velas criam um clima de luminosidade propícia a volúpia, luxúria e aos maus costumes. Quando perfumadas servem para atrapalhar a degustação de vinhos e interferir nos aromas dos pratos, bem como desodorizar locais catinguentos, segundo versão publicada no outro blog.

Porém a simbologia maior do uso das velas permanece, ainda, relacionada com os eventos natalícios. Nada a ver com Natal e sim com aniversários. Nestas comemorações comete-se a grosseria de dispor uma vela para cada ano de vida do aniversariante. Às vezes em cima de bolinhos mixurucas, o que acentua a disparidade entre intenção e incivilidade. Isto tudo acompanhado de cantorias e pique-pique. Assim não há como não odiar velas. Mesmo as decorativas.

PS: ofereço este post em reverência às poucas velinhas acesas ontem no aniversário, de .... alguns anos, da minha irmãzinha.
