Referências Bibliográficas Autores História da Matemática na Europa Ocidental Abraham bar Hiyya Abraham bar Hiyya, foi um matemático e astrónomo judeu que viveu em Espanha. Também conhecido pelo seu nome em latim Savarsoda, que significa governador da cidade, foi, provavelmente educado num dos principados árabes do califado de Córdova. Mas, foi em Barcelona que Abraham escreveu as suas obras originais em hebreu. Conhecem-se duas obras com conteúdos matemáticos: - a primeira enciclopédia escrita em hebreu, sobre matemática, astronomia, óptica e música, Yesodey ha-Tevuna u-Migdal ha-Emuna - e uma obra de geometria prática, Hibbur ha-Meshiha we-ha-Tishboret, Tratado da medida e cálculo) , de 1116. Este tratado foi traduzido para latim, em 1145, por Plato de Tivoli, com o nome Liber embadorum Embora este tratado tivesse como objectivo ajudar os judeus espanhóis e franceses no cálculo da medição dos campos, nele encontram-se algumas definições, axiomas e teoremas de Euclides. Nele encontram-se justificações geométricas, ao estilo islâmico, para justificar problemas algébricos, incluindo as equações do 2º grau. Alguns problemas do Tratado da medida e cálculo Problema Se da área de um quadrado subtrairmos a soma dos [quatro] lados e sobrar 21, qual é a área do quadrado e qual é o comprimento de cada um dos lados iguais?
