Cecilia was known to be Ludovico’s favorite and most admired companion.\n\nCecilia Gallerani is portrayed in a three-quarter pose, a perspective that was revolutionary at the time. Her gaze is gentle yet confident, exuding a sense of calm poise.\n\nThe ermine was an emblem used by Ludovico Sforza, who was sometimes called the 'White Ermine', and the presence of the ermine in the painting may allude to their intimate connection. The ermine, often associated with purity and honor due to its pristine white fur, might also symbolize the purity of Cecilia.\n\nLeonardo's meticulous attention to detail is evident in the painting, from the softness of Gallerani's skin to the texture of the ermine. His use of sfumato is evident in the delicate rendering of the lady's features.\n\nThe painting currently resides in the National Museum in Krakow, Poland.","4b0e000f-241e-4376-ada2-bc3c5d4d22ba",[1146,1165,1176],{"id":1147,"data":1148,"type":66,"version":25,"maxContentLevel":35},"d8dc77cb-005e-4c0f-9392-4a868e72e142",{"type":66,"reviewType":35,"spacingBehaviour":25,"collapsingSiblings":1149,"multiChoiceQuestion":1153,"multiChoiceCorrect":1155,"multiChoiceIncorrect":1157,"multiChoiceMultiSelect":6,"multiChoiceRevealAnswerOption":6,"matchPairsQuestion":1161,"matchPairsPairs":1162},[1150,1151,1152],"a8c48898-e5a7-4ecb-85d8-1b3632b8a5c5","70653859-4c39-4855-ac02-ccca16483933","0b920f9d-5a19-4fe3-b5fe-cb0f4545db32",[1154],"Who was the Milanese mistress of Ludovico Sforza, depicted in 'Lady with an Ermine'?",[1156],"Cecilia Gallerani",[1158,1159,1160],"Lisa Gherardini","Anne of Brittany","Dianne Modestini",[132],[1163],{"left":1156,"right":1164,"direction":35},"Milanese mistress of Ludovico Sforza",{"id":1166,"data":1167,"type":66,"version":25,"maxContentLevel":35},"48587bcf-6fee-4b0b-8dc0-538b7b7d8d92",{"type":66,"reviewType":35,"spacingBehaviour":25,"multiChoiceQuestion":1168,"multiChoiceCorrect":1170,"multiChoiceIncorrect":1172,"multiChoiceMultiSelect":6,"multiChoiceRevealAnswerOption":6},[1169],"How is Cecilia Gallerani portrayed in 'Lady with an Ermine'?",[1171],"In a three-quarter pose",[1173,1174,1175],"In a full frontal pose","In a side profile","In a one-quarter pose",{"id":865,"data":1177,"type":66,"version":35,"maxContentLevel":35},{"type":66,"reviewType":35,"spacingBehaviour":25,"collapsingSiblings":1178,"multiChoiceQuestion":1179,"multiChoiceCorrect":1181,"multiChoiceIncorrect":1182,"multiChoiceMultiSelect":6,"multiChoiceRevealAnswerOption":6,"matchPairsQuestion":1183,"matchPairsPairs":1184},[861,864,866],[1180],"What is the significance of the famous ermine in Leonardo's painting?",[972],[870,872,874],[132],[1185],{"left":1186,"right":873,"direction":35},"Ermine in the painting",{"id":1188,"data":1189,"type":21,"version":21,"maxContentLevel":35,"summaryPage":1191,"introPage":1199,"pages":1205},"4f6c6665-de6f-42f6-9a8b-9ca89e19c1b1",{"type":21,"title":1190},"The Virgin of the Rocks",{"id":1192,"data":1193,"type":35,"maxContentLevel":35,"version":25},"feb063f0-af84-4af6-bf0e-9347727c8611",{"type":35,"summary":1194},[1195,1196,1197,1198],"Leonardo da Vinci painted the 'Virgin of the Rocks' for a religious brotherhood in Milan","The painting shows the Virgin Mary, infant Jesus, John the Baptist, and archangel Uriel in a rocky setting","There are two versions of the painting: one in the Louvre and one in the National Gallery in London","The 'Virgin of the Rocks' project led to Leonardo's grander commissions like 'The Last Supper'",{"id":1200,"data":1201,"type":52,"maxContentLevel":35,"version":25},"f9ab7d36-1650-4a00-8e87-1a160c51b049",{"type":52,"intro":1202},[1203,1204],"What symbolism is hidden in the 'Virgin of The Rocks' setting?","Why did Leonardo create two versions of 'Virgin of The Rocks'?",[1206,1230,1258,1263,1291],{"id":1207,"data":1208,"type":25,"maxContentLevel":35,"version":21,"reviews":1211},"99ed2a38-bc63-4f97-b13c-8cd96ea5993a",{"type":25,"markdownContent":1209,"audioMediaId":1210},"One of the most famous works from Leonardo's so-called First Milanese Period is the 'Virgin of The Rocks'.\n\n![Graph](image://23a5a593-d591-4be1-8d55-665ad2a89a01 \"Painting of Virgin of The Rocks.
