“Perhaps only 1” 的翻译

【 英语 】
Perhaps only 15 of his paintingshave survived, partly because his constant experimentation with new techniquesmade his total output quite small. Although not a prolific painter, Leonardo was a mostproductive draftsman, keeping journals full of sketches, drawings, and diagrams.

也许只有15幅作品幸存下来，部分原因是他不断尝试新技术，使得他的总作品量相当小。虽然不是一个多产的画家，但莱昂纳多是一个最有生产力的绘图员，他的日记里写满了素描、素描和图表。
