1534-1584,Painter, tapestry designer, draughtsman and poet. He was probably trained by his parents. The suggestion that he became a member of the Ghent Guild of St Luke before 1540 was derived from an incorrect interpretation of the Guild records for 1574-5. Van Mander recorded that, as a boy, de Heere accompanied his father on his trips to the stone-quarries of the Meuse region, where he made topographical drawings. Lucas was sent to Frans Floris's studio c. 1555 or shortly before to complete his training, and he may have collaborated with his master on tapestry cartoons and stained-glass designs, although no cartoons or preparatory drawings survive. During this period de Heere also became noted as a poet in the local rhetoricians' chambers. His father's influence helped him to gain commissions in Ghent from 1555, and, according to Marcus van Vaernewijck (1568), he worked on new stained-glass windows for the St Janskerk in Ghent in the same year.
