All rights reserved.We identify a spectroscopic sequence of galaxies, analogous to the Hubble sequence of morphological types, based on the Automatic Spectroscopic K-means-based (ASK) classification. Considering galaxy spectra as multidimensional vectors, the majority of the spectral classes are distributed along a well-defined curve going from the earliest to the latest types, suggesting that the optical spectra of normal galaxies can be described in terms of a single affine parameter. Optically bright active galaxies, however, appear as an independent, roughly orthogonal branch that intersects the main sequence exactly at the transition between early and late typesThis work has been funded by projects AYA2007-67965-C03-03, AYA 2007-67965-C03-01, AYA2007-67752-C03-01 and CSD 2006-00070 (Spanish Ministry of Science, Technology and Innovation

    This article examines the intersection of spectatorship, literary imagination, and medical discourse as they converge in Celestina.  The representation of dead bodies in this text projects Rojas’ work into early modernity as a literary forerunner of the anatomical discourse that scrutinizes the interior of the body and which would not emerge in the Iberian Peninsula until the 1540s. Drawing on Visual Studies, Body Studies, and Literary Studies, the present essay interrogates the notion of the gaze and the representation of cadavers in Celestina as a transgressive narrative that in 1499 tests the boundaries between real and metaphorical anatomies. From this perspective, Rojas’ literary imagination vis à vis the shift from a medieval to a pre-modern medical gaze inform a post-medieval understanding of the concept of the dead body at the dawn of modernity in Iberia
